This syndrome is an X-linked inheritance disease and it is caused by mutations in the human androgen receptor (AR) gene. Non-synonymous point AR mutations are frequently described in this disease, including in the complete phenotype. We present a novel synonymous mutation in the human AR gene (c.1530C > T) in four 46,XY patients from two unrelated families associated with complete androgen insensitivity syndrome (CAIS). The analysis of mRNA from testis showed that synonymous AR mutation changed the natural exon 1 donor splice site, with deletion of the last 92 nucleotides of the AR exon 1 leading to a premature stop codon 12 positions ahead resulting in a truncate AR protein. Linkage analyses suggested a probable founder effect for this mutation. In conclusion, we described the first synonymous AR mutation associated with CATS phenotype, reinforcing the disease-causing role of synonymous mutations
conferenceObject Obese Prader-Willi versus Obese Controls: Metabolic Profile in Brazilian Patients(2015) ITO, S.; JERONIMO, T.; FARIA JUNIOR, J.; PASSONE, C. de Gouveia Buff; FRANCO, R. Rocha; STEINMETZ, L.; KUPERMAN, H.; DAMIANI, D.- Psychosexual Aspects, Effects of Prenatal Androgen Exposure, and Gender Change in 46,XY Disorders of Sex Development(2019) BATISTA, Rafael Loch; INACIO, Marlene; ARNHOLD, Ivo Jorge Prado; GOMES, Nathalia Lisboa; FARIA JR., Jose Antonio Diniz; MORAES, Daniela Rodrigues de; COSTA, Elaine Maria Frade; DOMENICE, Sorahia; MENDONCA, Berenice BilharinhoContext: In 46,XY disorders of sexual development (DSD) patients, several factors may affect psychosexual development, leading to gender identity discrepancy and gender change later in life. Prenatal sexual steroid exposure and external genital virilization are considered to influence human psychosexual development, but their roles not completely understood yet. Design: A total of 144 individuals (18 to 60 years of age) with a clinical/molecular diagnosis of 46,XY DSD from a single tertiary center were enrolled. Psychosexual outcomes (gender role, gender identity, and sexual orientation) were assessed using questionnaires and psychological test. The Sinnecker score was used for genital virilization measurement. Prenatal androgen exposure was estimated according to 46,XY DSD etiology. Results: We found a positive association between prenatal androgen exposure and male psychosexual outcomes. Alternatively, prenatal estrogen exposure, age of gonadectomy, and the degree of external genital virilization did not influence any psychosexual outcome. There were 19% (n = 27) with gender change, which was associated with prenatal androgen exposure (P < 0.001) but not with the external genital virilization. The median age of gender change was 15 years, but most of the patients reported the desire for gender change earlier. Conclusions: Prenatal androgen exposure influenced psychosexual development in 46,XY DSD favoring male psychosexuality in all psychosexual outcomes, whereas the degree of external genital virilization did not influence these outcomes. The organizational effect of sexual steroids on psychosexuality at puberty appears to be weak in comparison with the prenatal effects. Prenatal androgen exposure also influenced female-to-male gender change frequency. All 46,XY DSD conditions with prenatal androgen exposure must be followed for gender issues in their management.
