Genetic Variant SWI5:p.Leu68Pro (chr9-128284601-T-C) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_001318089.2(SWI5):c.203T>C(p.Leu68Pro) variant causes a missense change. The variant allele was found at a frequency of 0.0000527 in 1,613,818 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. L68R) has been classified as Uncertain significance.
