Genes affected

AGAP1 (HGNC:16922): (ArfGAP with GTPase domain, ankyrin repeat and PH domain 1) This gene encodes a member of an ADP-ribosylation factor GTPase-activating protein family involved in membrane trafficking and cytoskeleton dynamics. This gene functions as a direct regulator of the adaptor-related protein complex 3 on endosomes. Multiple transcript variants encoding different isoforms have been found for this gene.

The c.107G>A (p.R36H) alteration is located in exon 1 (coding exon 1) of the AGAP1 gene. This alteration results from a G to A substitution at nucleotide position 107, causing the arginine (R) at amino acid position 36 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
