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]

Collection Method: clinical testing

The c.752C>T (p.P251L) 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 752, causing the proline (P) at amino acid position 251 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
