Genetic Variant PSTPIP2:p.Arg32His (chr18-46039986-C-T) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_024430.4(PSTPIP2):c.95G>A(p.Arg32His) variant causes a missense change. The variant allele was found at a frequency of 0.0000123 in 1,461,268 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. R32L) has been classified as Uncertain significance.
