Genetic Variant NIPSNAP3A:p.Pro140Arg (chr9-104753053-C-G) – 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_015469.3(NIPSNAP3A):c.419C>G(p.Pro140Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,461,042 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. P140L) has been classified as Uncertain significance.
