Growth Hormone Deficiency and Cryptorchidism in a Family with Xq26.3 Duplication and Position Effect on SOX3

Reschke Felix , Jahn Arne , Tzschach Andreas , Schallner Jens , Hagen Maja von der , Huebner Angela

SOX3 is located on the X-chromosome (Xq27.1) and encodes a SRY-related protein that acts as a developmental transcription factor. Copy Number Variations (losses and gains), mutations of polyalanine stretches (deletions or expansions) and missense mutations of SOX3 have been associated with growth hormone deficiency with incomplete penetrance, hypogonadism, differences of sexual development and variable additional endocrine disorders (MIM #312000 and #300123)....
