Abstract: | 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 |
