Atypical Clinical Presentation of Persistent Müllerian Duct Syndrome in Siblings

Abstract : Persistent Müllerian duct syndrome (PMDS) is a rare autosomal recessive disorder characterized by the lack of regression of the derivatives of the Müllerian ducts in males. Boys with this condition usually present with unilateral or bilateral cryptorchidism, inguinal hernias, and reproductive disorders with normal male genitalia. Variants in the AMH or AMHR2 genes are responsible for the development of this syndrome. The genetic diagnosis and surgery in PMDS is challenging for both the endocrinologist and the urologist. Here, we describe the management of 2 siblings from 1 family who presented with bilateral cryptorchidism and hypospadias at birth. One child had testis located in the pelvis in the position of normal ovaries, while the other child had testis which were located in the inguinal canals (bilateral inguinal cryptorchidism). Exome sequencing revealed a compound heterozygous variant in the AMHR2 gene c.1388G>A, p.R463H and c.1412G>A p.R471H. To our knowledge, hypospadias has not been described in association with PMDS.
