Genes affected

SHROOM4 (HGNC:29215): (shroom family member 4) This gene encodes a member of the APX/Shroom family, which contain an N-terminal PDZ domain and a C-terminal ASD2 motif. The encoded protein may play a role in cytoskeletal architecture. Mutations in this gene have been linked to the X-linked Stocco dos Santos syndrome characterized by cognitive disabilities. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2017]

The c.4352A>G (p.Y1451C) alteration is located in exon 9 (coding exon 9) of the SHROOM4 gene. This alteration results from a A to G substitution at nucleotide position 4352, causing the tyrosine (Y) at amino acid position 1451 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
