Genes affected
DENND5A (HGNC:19344): (DENN domain containing 5A) This gene encodes a DENN-domain-containing protein that functions as a RAB-activating guanine nucleotide exchange factor (GEF). This protein catalyzes the conversion of GDP to GTP and thereby converts inactive GDP-bound Rab proteins into their active GTP-bound form. The encoded protein is recruited by RAB6 onto Golgi membranes and is therefore referred to as RAB6-interacting protein 1. This protein binds with RAB39 as well. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Mutations in this gene are associated with early infantile epileptic encephalopathy-49.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DENND5A. . Gene score misZ 2.3781 (greater than the threshold 3.09). Trascript score misZ 3.1917 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy, 49, Tourette syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.10871944).
