dbSNP rs1422760130: CALHM3:p.Leu301Arg (chr10-103473346-A-C) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_001129742.2(CALHM3):c.902T>G(p.Leu301Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000199 in 1,505,370 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. L301F) has been classified as Uncertain significance.
