Genes affected

RAPH1 (HGNC:14436): (Ras association (RalGDS/AF-6) and pleckstrin homology domains 1) This gene encodes a protein that belongs to the Mig10/Rap1-interacting adaptor molecule/Lamellipodin family of adapter proteins, which function in cell migration. Members of this family contain pleckstrin-homology domains, Ras-association domains, and proline-rich C-termini. The protein encoded by this gene regulates actin dynamics through interaction with Ena/Vasodilator proteins as well as direct binding to filamentous actin to regulate actin network assembly. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]

RAPH1 links:

ABI2 (HGNC:24011): (abl interactor 2) Enables several functions, including SH3 domain binding activity; identical protein binding activity; and ubiquitin protein ligase binding activity. Contributes to small GTPase binding activity. Involved in Rac protein signal transduction; positive regulation of cellular component organization; and zonula adherens assembly. Acts upstream of or within peptidyl-tyrosine phosphorylation. Located in several cellular components, including filopodium tip; lamellipodium; and nucleoplasm. Part of SCAR complex. Is active in adherens junction. Colocalizes with actin filament. [provided by Alliance of Genome Resources, Apr 2022]

The c.3016C>A (p.P1006T) alteration is located in exon 14 (coding exon 13) of the RAPH1 gene. This alteration results from a C to A substitution at nucleotide position 3016, causing the proline (P) at amino acid position 1006 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
