Duplications and deletions of Xq26-27 including SOX3 (Xq27.1) have been associated with X-linked mental retardation and isolated growth hormone deficiency (OMIM 300123) or X-linked panhypopituitarism (OMIM 312000).

In humans, over- and underdosage of SOX3 is associated with X-linked hypopituitarism with variable phenotypes ranging from isolated GH deficiency (GHD) to panhypopituitarism, with or without mental retardation and, in most cases, with reported pituitary imaging, an ectopic/undescended posterior pituitary.

Mutations in the GH1 and GHRHR genes shed light on the phenotype and pathogenesis of IGHD whereas mutations in transcription factors such as HESX1, PROP1, POU1F1, LHX3, LHX4, GLI2 and SOX3 contributed to the understanding of CPHD.

However, a number of familial cases have been described and the identification of mutations in key developmental genes including HESX1, SOX2 and SOX3 in patients with SOD and associated phenotypes suggests that a genetic causation is likely in the more common sporadic cases of the condition.
