Mental Retardation, X-linked (SOX3)


Dred_IDRD00026
OMIM ID300123
Disease nameMental Retardation, X-linked
Alternative namesMental retardation, X-linked, with isolated growth hormone deficiency
CategoryGenetic diseases, Mental diseases, Neuronal diseases, Endocrine diseases, Rare diseases
PhenotypeOMIM: Hamel et al. reported a family in which males in 3 generations had varying degrees of mental retardation, isolated growth hormone deficiency, and infantile behavior but without other consistent phenotypic abnormalities. The pedigree was consistent with X-linked inheritance. The male patients continued to grow until well into their twenties and reached a height ranging from 135 to 159 cm [PubMed: 8826446].

Gene DescriptionThis gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins. Mutations in this gene have been associated with X-linked cognitive disability with growth hormone deficiency. [provided by RefSeq, Jul 2008]
