Genes affected

GNA11 (HGNC:4379): (G protein subunit alpha 11) The protein encoded by this gene belongs to the family of guanine nucleotide-binding proteins (G proteins), which function as modulators or transducers in various transmembrane signaling systems. G proteins are composed of 3 units: alpha, beta and gamma. This gene encodes one of the alpha subunits (subunit alpha-11). Mutations in this gene have been associated with hypocalciuric hypercalcemia type II (HHC2) and hypocalcemia dominant 2 (HYPOC2). Patients with HHC2 and HYPOC2 exhibit decreased or increased sensitivity, respectively, to changes in extracellular calcium concentrations. [provided by RefSeq, Dec 2013]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), GNA11. . Gene score misZ 3.768 (greater than the threshold 3.09). Trascript score misZ 3.8723 (greater than threshold 3.09). GenCC has associacion of gene with autosomal dominant hypocalcemia, familial hypocalciuric hypercalcemia 2, autosomal dominant hypocalcemia 2.

BP4

Computational evidence support a benign effect (MetaRNN=0.33533892).

BS2

High AC in GnomAdExome4 at 7 AD gene.

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 8 of the GNA11 protein (p.Ala8Val). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with GNA11-related conditions. ClinVar contains an entry for this variant (Variation ID: 1362827). 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 tolerated. In 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. -
