Genes affected

SSH3 (HGNC:30581): (slingshot protein phosphatase 3) The ADF (actin-depolymerizing factor)/cofilin family (see MIM 601442) is composed of stimulus-responsive mediators of actin dynamics. ADF/cofilin proteins are inactivated by kinases such as LIM domain kinase-1 (LIMK1; MIM 601329). The SSH family appears to play a role in actin dynamics by reactivating ADF/cofilin proteins in vivo (Niwa et al., 2002 [PubMed 11832213]).[supplied by OMIM, Mar 2008]

The c.334C>T (p.R112C) alteration is located in exon 3 (coding exon 3) of the SSH3 gene. This alteration results from a C to T substitution at nucleotide position 334, causing the arginine (R) at amino acid position 112 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
