Genetic Variant TRPC7:p.Ala760Gly (chr5-136225338-G-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_020389.3(TRPC7):c.2279C>G(p.Ala760Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,846 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. 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. A760V) has been classified as Uncertain significance.
