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.

Apr 12, 2022

The c.203C>T (p.S68F) alteration is located in exon 1 (coding exon 1) of the AGAP1 gene. This alteration results from a C to T substitution at nucleotide position 203, causing the serine (S) at amino acid position 68 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
