Genetic Variant CERCAM:p.Arg334Pro (chr9-128428967-G-C) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_016174.5(CERCAM):c.1001G>C(p.Arg334Pro) variant causes a missense change. The variant allele was found at a frequency of 0.0000143 in 1,611,270 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. R334Q) has been classified as Uncertain significance.
