Description

The MYH9 c.422A>G variant is predicted to result in the amino acid substitution p.Lys141Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
