Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_016063.3(HDDC2):c.215G>A(p.Arg72His) variant causes a missense change. The variant allele was found at a frequency of 0.0000192 in 1,612,454 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R72C) has been classified as Uncertain significance.
