    46,XY disorder of sex development (DSD) due to 17 beta-hydroxysteroid dehydrogenase type 3 deficiency
    (2017) MENDONCA, Berenice B.; GOMES, Nathalia Lisboa; COSTA, Elaine M. F.; INACIO, Marlene; MARTIN, Regina M.; NISHI, Mirian Y.; CARVALHO, Filomena Marino; TIBOR, Francisco Denes; DOMENICE, Sorahia
    17 beta-hydroxysteroid dehydrogenase 3 deficiency consists of a defect in the last phase of steroidogenesis, in which androstenedione is converted into testosterone and estrone into estradiol. External genitalia range from female-like to atypical genitalia and most affected males are raised as females. Virilization in subjects with 17 beta-HSD3 deficiency occurs at the time of puberty and several of them change to male social sex. In male social sex patients, testes can be safely maintained, as long as they are positioned inside the scrotum The phenotype of 46,XY DSD due to 17 beta-HSD3 deficiency is extremely variable and clinically indistinguishable from other causes of 46,XY DSD such as partial androgen insensitivity syndrome and 5 alpha-reductase 2 deficiency. Laboratory diagnosis is based on a low testosterone/androstenedione ratio due to high serum levels of androstenedione and low levels of testosterone. The disorder is caused by a homozygous or compound heterozygous mutations in the HSD17B3 gene that encodes the 17 beta-HSD3 isoenzyme leading to an impairment of the conversion of 17-keto into 17-hydroxysteroids. Molecular genetic testing confirms the diagnosis and provides the orientation for genetic counseling. Our proposal in this article is to review-the previously reported cases of 17 beta-HSD3 deficiency adding our own cases. (C) 2016 Published by Elsevier Ltd.

    Heterozygous Nonsense Mutation in the Androgen Receptor Gene Associated with Partial Androgen Insensitivity Syndrome in an Individual with 47, XXY Karyotype
    (2017) BATISTA, Rafael L.; RODRIGUES, Andresa S.; NISHI, Mirian Y.; FEITOSA, Alina C. R.; GOMES, Nathalia L. R. A.; JUNIOR, Jose Antonio F.; DOMENICE, Sorahia; COSTA, Elaine M. F.; MENDONCA, Berenice B. de
    There are only 2 patients with 47, XXY karyotype and androgen receptor (AR) gene mutation reported in the literature, and both are diagnosed as complete androgen insensitivity syndrome (CAIS). We report a 22-year-old female with 47, XXY karyotype and atypical external genitalia. Sequencing of AR revealed the heterozygous p.Asn849Lys*32 mutation, and extensive X chromosome microsatellite analysis showed homozygosity for Xp and heterozygosity for Xq, suggesting partial X maternal isodisomy. Partial androgen insensitivity syndrome (PAIS) developed in this case, probably because of the presence of the heterozygous AR mutation and random X-inactivation of the healthy allele. This is the first report of a female patient with 47, XXY karyotype and PAIS phenotype. (C) 2017 S.Karger AG, Basel

    Wide spectrum of NR5A1-related phenotypes in 46,XY and 46,XX individuals
    (2016) DOMENICE, Sorahia; MACHADO, Aline Zamboni; FERREIRA, Frederico Moraes; FERRAZ-DE-SOUZA, Bruno; LERARIO, Antonio Marcondes; LIN, Lin; NISHI, Mirian Yumie; GOMES, Nathalia Lisboa; SILVA, Thatiana Evelin da; SILVA, Rosana Barbosa; CORREA, Rafaela Vieira; MONTENEGRO, Luciana Ribeiro; NARCISO, Amanda; COSTA, Elaine Maria Frade; ACHERMANN, John C.; MENDONCA, Berenice Bilharinho
    Steroidogenic factor 1 (NR5A1, SF-1, Ad4BP) is a transcriptional regulator of genes involved in adrenal and gonadal development and function. Mutations in NR5A1 have been among the most frequently identified genetic causes of gonadal development disorders and are associated with a wide phenotypic spectrum. In 46,XY individuals, NR5A1-related phenotypes may range from disorders of sex development (DSD) to oligo/azoospermia, and in 46,XX individuals, from 46,XX ovotesticular and testicular DSD to primary ovarian insufficiency (POI). The most common 46,XY phenotype is atypical or female external genitalia with clitoromegaly, palpable gonads, and absence of Mullerian derivatives. Notably, an undervirilized external genitalia is frequently seen at birth, while spontaneous virilization may occur later, at puberty. In 46,XX individuals, NR5A1 mutations are a rare genetic cause of POI, manifesting as primary or secondary amenorrhea, infertility, hypoestrogenism, and elevated gonadotropin levels. Mothers and sisters of 46,XY DSD patients carrying heterozygous NR5A1 mutations may develop POI, and therefore require appropriate counseling. Moreover, the recurrent heterozygous p.Arg92Trp NR5A1 mutation is associated with variable degrees of testis development in 46,XX patients. A clear genotype-phenotype correlation is not seen in patients bearing NR5A1 mutations, suggesting that genetic modifiers, such as pathogenic variants in other testis/ovarian-determining genes, may contribute to the phenotypic expression. Here, we review the published literature on NR5A1-related disease, and discuss our findings at a single tertiary center in Brazil, including ten novel NR5A1 mutations identified in 46,XY DSD patients. The ever-expanding phenotypic range associated with NR5A1 variants in XY and XX individuals confirms its pivotal role in reproductive biology, and should alert clinicians to the possibility of NR5A1 defects in a variety of phenotypes presenting with gonadal dysfunction.

    Cytogenomic Investigation of Syndromic Brazilian Patients with Differences of Sexual Development
    (2023) JR, Jose Antonio Diniz Faria; MORAES, Daniela R.; KULIKOWSKI, Leslie Domenici; BATISTA, Rafael Loch; GOMES, Nathalia Lisboa; NISHI, Mirian Yumie; ZANARDO, Evelin; NONAKA, Carolina Kymie Vasques; SOUZA, Bruno Solano de Freitas; MENDONCA, Berenice Bilharinho; DOMENICE, Sorahia
    Background: Cytogenomic methods have gained space in the clinical investigation of patients with disorders/differences in sexual development (DSD). Here we evaluated the role of the SNP array in achieving a molecular diagnosis in Brazilian patients with syndromic DSD of unknown etiology. Methods: Twenty-two patients with DSD and syndromic features were included in the study and underwent SNP-array analysis. Results: In two patients, the diagnosis of 46,XX SRY + DSD was established. Additionally, two deletions were revealed (3q29 and Xp22.33), justifying the syndromic phenotype in these patients. Two pathogenic CNVs, a 10q25.3-q26.2 and a 13q33.1 deletion encompassing the FGFR2 and the EFNB2 gene, were associated with genital atypia and syndromic characteristics in two patients with 46,XY DSD. In a third 46,XY DSD patient, we identified a duplication in the 14q11.2-q12 region of 6.5 Mb associated with a deletion in the 21p11.2-q21.3 region of 12.7 Mb. In a 46,XY DSD patient with delayed neuropsychomotor development and congenital cataracts, a 12 Kb deletion on chromosome 10 was found, partially clarifying the syndromic phenotype, but not the genital atypia. Conclusions: The SNP array is a useful tool for DSD patients, identifying the molecular etiology in 40% (2/5) of patients with 46,XX DSD and 17.6% (3/17) of patients with 46,XY DSD.

    Variants in 46,XY DSD-Related Genes in Syndromic and Non-Syndromic Small for Gestational Age Children with Hypospadias
    (2022) BRAGA, B. L.; GOMES, N. L.; NISHI, M. Y.; FREIRE, B. L.; BATISTA, R. L.; FARIA JUNIOR, J. A. D.; FUNARI, M. F. A.; BENEDETTI, A. F. F.; NARCIZO, A. De Moraes; CARDOSO, L. Cavalca; LERARIO, A. M.; GUERRA-JUNIOR, G.; COSTA, E. M. F.; DOMENICE, S.; JORGE, A. A. L.; MENDONCA, B. B.
    Hypospadias is a common congenital disorder of male genital formation. Children born small for gestational age (SGA) present a high frequency of hypospadias of undetermined etiology. No previous study investigated the molecular etiology of hypospadias in boys born SGA using massively parallel sequencing. Our objective is to report the genetic findings of a cohort of patients born SGA with medium or proximal hypospadias. We identified 46 individuals with this phenotype from a large cohort of 46,XY DSD patients, including 5 individuals with syndromic features. DNA samples from subjects were studied by either whole exome sequencing or target gene panel approach. Three of the syndromic patients have 5 main clinical features of Silver-Russell syndrome (SRS) and were first studied by MLPA. Among the syndromic patients, loss of DNA methylation at the imprinting control region H19/IGF2 was identified in 2 individuals with SRS clinical diagnosis. Two novel pathogenic variants in compound heterozygous state were identified in the CUL7 gene establishing the diagnosis of 3M syndrome in one patient, and a novel homozygous variant in TRIM37 was identified in another boy with Mulibrey nanism phenotype. Among the non-syndromic subjects, 7 rare heterozygous variants were identified in 6 DSD-related genes. However, none of the variants found can explain the phenotype by themselves. In conclusion, a genetic defect that clarifies the etiology of hypospadias was not found in most of the non-syndromic SGA children, supporting the hypothesis that multifactorial causes, new genes, and/or unidentified epigenetic defects may have an influence in this condition.

    Mutations in MAP3K1 that cause 46,XY disorders of sex development disrupt distinct structural domains in the protein
    (2019) CHAMBERLIN, Adam; HUETHER, Robert; MACHADO, Aline Z.; GRODEN, Michael; LIU, Hsiao-Mei; UPADHYAY, Kinnari; VIVIAN, O.; GOMES, Nathalia L.; LERARIO, Antonio M.; NISHI, Mirian Y.; COSTA, Elaine M. F.; MENDONCA, Berenice; DOMENICE, Sorahia; VELASCO, Jacqueline; LOKE, Johnny; OSTRER, Harry
    Missense mutations in the gene, MAP3K1, are a common cause of 46,XY gonadal dysgenesis, accounting for 15-20% of cases [Ostrer, 2014, Disorders of sex development (DSDs): an update. J. Clin. Endocrinol. Metab., 99, 1503-1509]. Functional studies demonstrated that all of these mutations cause a protein gain-of-function that alters co-factor binding and increases phosphorylation of the downstream MAP kinase pathway targets, MAPK11, MAP3K and MAPK1. This dysregulation of the MAP kinase pathway results in increased CTNNB1, increased expression of WNT4 and FOXL2 and decreased expression of SRY and SOX9. Unique and recurrent pathogenic mutations cluster in three semi-contiguous domains outside the kinase region of the protein, a newly identified N-terminal domain that shares homology with the Guanine Exchange Factor (residues Met164 to Glu231), a Plant HomeoDomain (residues Met442 to Trp495) and an ARMadillo repeat domain (residues Met566 to Glu862). Despite the presence of the mutation clusters and clinical data, there exists a dearth of mechanistic insights behind the development imbalance. In this paper, we use structural modeling and functional data of these mutations to understand alterations of the MAP3K1 protein and the effects on protein folding, binding and downstream target phosphorylation. We show that these mutations have differential effects on protein binding depending on the domains in which they occur. These mutations increase the binding of the RHOA, MAP3K4 and FRAT1 proteins and generally decrease the binding of RAC1. Thus, pathologies in MAP3K1 disrupt the balance between the pro-kinase activities of the RHOA and MAP3K4 binding partners and the inhibitory activity of RAC1.
