Genetic Variant LDAH:p.Arg159Gly (chr2-20740199-G-C) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_021925.4(LDAH):c.475C>G(p.Arg159Gly) variant causes a missense change. The variant allele was found at a frequency of 0.0000186 in 1,609,196 control chromosomes in the GnomAD database, including 1 homozygotes. 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. R159H) has been classified as Uncertain significance.
