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.4084T>C (p.F1362L) alteration is located in exon 8 (coding exon 8) of the SHROOM4 gene. This alteration results from a T to C substitution at nucleotide position 4084, causing the phenylalanine (F) at amino acid position 1362 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
