Genetic Variant PARD3B:p.His49Tyr (chr2-204686205-C-T) – 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_001302769.2(PARD3B):c.145C>T(p.His49Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,459,546 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. H49D) has been classified as Uncertain significance.
