Genes affected

ASAP3 (HGNC:14987): (ArfGAP with SH3 domain, ankyrin repeat and PH domain 3) This gene encodes a member of a subfamily of ADP-ribosylation factor(Arf) GTPase-activating proteins that contain additional ankyrin repeat and pleckstrin homology domains. The Arf GAP domain of this protein catalyzes the hydrolysis of GTP bound to Arf proteins. The encoded protein promotes cell differentiation and migration and has been implicated in cancer cell invasion. Alternative splicing results in multiple transcript variants.

The c.2573G>A (p.R858Q) alteration is located in exon 24 (coding exon 24) of the ASAP3 gene. This alteration results from a G to A substitution at nucleotide position 2573, causing the arginine (R) at amino acid position 858 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
