Genes affected

WASL (HGNC:12735): (WASP like actin nucleation promoting factor) This gene encodes a member of the Wiskott-Aldrich syndrome (WAS) protein family. Wiskott-Aldrich syndrome proteins share similar domain structure, and associate with a variety of signaling molecules to alter the actin cytoskeleton. The encoded protein is highly expressed in neural tissues, and interacts with several proteins involved in cytoskeletal organization, including cell division control protein 42 (CDC42) and the actin-related protein-2/3 (ARP2/3) complex. The encoded protein may be involved in the formation of long actin microspikes, and in neurite extension. [provided by RefSeq, Jul 2013]

The c.388T>A (p.F130I) alteration is located in exon 4 (coding exon 4) of the WASL gene. This alteration results from a T to A substitution at nucleotide position 388, causing the phenylalanine (F) at amino acid position 130 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
