dbSNP rs576683687: CPLANE2:p.Arg203Pro (chr1-16232217-C-G) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_030907.4(CPLANE2):c.608G>C(p.Arg203Pro) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,078 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. R203W) has been classified as Uncertain significance.
