Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_013326.5(RMC1):​c.65C>T​(p.Pro22Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000208 in 1,442,174 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. P22H) has been classified as Likely benign.
