Genetic Variant CALHM6:p.Gly52Cys (chr6-116462083-G-T) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_001010919.3(CALHM6):c.154G>T(p.Gly52Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000103 in 1,546,480 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. G52S) has been classified as Uncertain significance.
