Genes affected

SSH1 (HGNC:30579): (slingshot protein phosphatase 1) The protein encoded by this gene belongs to the slingshot homolog (SSH) family of phosphatases, which regulate actin filament dynamics. The SSH proteins dephosphorylate and activate the actin binding/depolymerizing factor cofilin, which subsequently binds to actin filaments and stimulates their disassembly. Cofilin is inactivated by kinases such as LIM domain kinase-1 (LIMK1), which may also be dephosphorylated and inactivated by SSH proteins. The SSH family thus appears to play a role in actin dynamics by reactivating cofilin proteins. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

The c.2881C>T (p.R961W) alteration is located in exon 15 (coding exon 15) of the SSH1 gene. This alteration results from a C to T substitution at nucleotide position 2881, causing the arginine (R) at amino acid position 961 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
