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 -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), 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=0.052037537).

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.2608C>T (p.P870S) alteration is located in exon 20 (coding exon 20) of the ARHGEF2 gene. This alteration results from a C to T substitution at nucleotide position 2608, causing the proline (P) at amino acid position 870 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
