Genes affected

WASF3 (HGNC:12734): (WASP family member 3) This gene encodes a member of the Wiskott-Aldrich syndrome protein family. The gene product is a protein that forms a multiprotein complex that links receptor kinases and actin. Binding to actin occurs through a C-terminal verprolin homology domain in all family members. The multiprotein complex serves to tranduce signals that involve changes in cell shape, motility or function. A pseudogene of this gene have been defined on chromosome 6. Alternative splicing results in multiple transcript variants [provided by RefSeq, May 2014]

The c.568C>T (p.R190C) alteration is located in exon 1 (coding exon 1) of the WASF3 gene. This alteration results from a C to T substitution at nucleotide position 568, causing the arginine (R) at amino acid position 190 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
