Genetic Variant KHDRBS2:p.Pro236Ser (chr6-61894739-G-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_152688.4(KHDRBS2):c.706C>T(p.Pro236Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,320 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign 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. P236T) has been classified as Uncertain significance.
