Description

The missense variant c.577T>C (p.Trp193Arg) in the TGM1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is absent in the gnomAD Exomes. The amino acid Tryptophan at position 193 is changed to an Arginine changing protein sequence and it might alter its composition and physico-chemical properties. The variant is predicted as damaging by SIFT. The amino acid change p.Trp193Arg in TGM1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
