Genes affected

ARHGEF2 (HGNC:682): (Rho/Rac guanine nucleotide exchange factor 2) Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The encoded protein may form complex with G proteins and stimulate rho-dependent signals. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Jun 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ARHGEF2. . Gene score misZ 3.6056 (greater than the threshold 3.09). Trascript score misZ 4.3595 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with midbrain and hindbrain malformations.

BP4

Computational evidence support a benign effect (MetaRNN=0.08319789).

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
