Genetic Variant MCMDC2:p.Pro315His (chr8-66883865-C-A) – 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_173518.5(MCMDC2):c.944C>A(p.Pro315His) variant causes a missense change. The variant allele was found at a frequency of 0.0000263 in 152,160 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. P315R) has been classified as Uncertain significance.
