Analysis of genetic and clinical characteristics of androgen insensitivity syndrome: a cohort study including 12 families.
Context: Androgen insensitivity syndrome (AIS) manifests itself as variable symptoms of under-virilization in patients with 46,XY disorders caused by androgen receptor (AR) gene variants. This large-sample study aimed to correlate the genotypes and phenotypes to the fertility of individuals.
Methods: This was a cohort study that analyzed the genetic and clinical characteristics of patients with AIS from a single center in China.
Results: The 117 patients were divided into 53 with complete AIS (CAIS) and 64 with partial AIS (PAIS). At their first visit, the median age was 1.83 years (0.92-4.17), and the external masculinization score was 3.0 (2.0-6.0). At the last follow-up, 92% (49/53) of patients with CAIS maintained their female gender, and 94% (60/64) of patients with PAIS were raised as males. No gender anxiety was observed in this study. Eighty-eight AR variants were identified, with 31 (35%) being unreported. Moreover, 24% (21/88) occurred more than once. The variants that appeared most frequently were located at amino acid 841, including p.R841H (n = 5) and p.R841C (n = 2). Variants p.N706S, p.R856H, and p.A871V were each observed 4 times. In terms of inheritance, 83% of patients with parental verification inherited variants from their mothers. We also observed that the variants from 1 case were inherited from his maternal grandfather who had hypospadias.
Conclusion: Most children with PAIS were raised as males. The abundance of maternally inheritable variants and the presence of case of preserved fertility indicate the fertility potential in patients with AIS. Hence, we recommend a careful evaluation of gonadectomy when fertility preservation is being considered.
期刊介绍:
European Journal of Endocrinology is the official journal of the European Society of Endocrinology. Its predecessor journal is Acta Endocrinologica.
The journal publishes high-quality original clinical and translational research papers and reviews in paediatric and adult endocrinology, as well as clinical practice guidelines, position statements and debates. Case reports will only be considered if they represent exceptional insights or advances in clinical endocrinology.
Topics covered include, but are not limited to, Adrenal and Steroid, Bone and Mineral Metabolism, Hormones and Cancer, Pituitary and Hypothalamus, Thyroid and Reproduction. In the field of Diabetes, Obesity and Metabolism we welcome manuscripts addressing endocrine mechanisms of disease and its complications, management of obesity/diabetes in the context of other endocrine conditions, or aspects of complex disease management. Reports may encompass natural history studies, mechanistic studies, or clinical trials.
Equal consideration is given to all manuscripts in English from any country.
