Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM2PM5PP2PP3_StrongPP5

The NM_002070.4(GNAI2):​c.536G>A​(p.Arg179His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000128 in 1,561,028 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R179C) has been classified as Uncertain significance.

Genes affected
GNAI2 (HGNC:4385): (G protein subunit alpha i2) The protein encoded by this gene is an alpha subunit of guanine nucleotide binding proteins (G proteins). The encoded protein contains the guanine nucleotide binding site and is involved in the hormonal regulation of adenylate cyclase. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]
