Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_031896.5(CACNG7):​c.242C>G​(p.Pro81Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P81L) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 31)
• Consequence: CACNG7 NM_031896.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.59

Genes affected

CACNG7 (HGNC:13626): (calcium voltage-gated channel auxiliary subunit gamma 7) The protein encoded by this gene is a type II transmembrane AMPA receptor regulatory protein (TARP). TARPs regulate both trafficking and channel gating of the AMPA receptors. This gene is part of a functionally diverse eight-member protein subfamily of the PMP-22/EMP/MP20 family and is located in a cluster with two family members, a type I TARP and a calcium channel gamma subunit.

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
