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.

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 23, 2023In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with AGAP1-related conditions. This variant is present in population databases (rs776418772, gnomAD 0.0009%). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 59 of the AGAP1 protein (p.Asn59Ser). -
