| Research Abstract |
Clinical analysis of mutation-positive patients indicated that loss of function of MAMLD1 leads to various clinical features including abnormal genitalia, testosterone deficiency, impaired spermatogenesis and infertility. In vitro assays suggested that Mamld1 enhances Cyp17a1 expression primarily in Leydig cells and permit to produce a sufficient amount of testosterone for male sex development. Collectively, it is likely that SF1-MAMLD1-CYP17A1 axis plays a critical role in regulation of testosterone production in the testis.
