The p.D157A variant (also known as c.470A>C), located in coding exon 4 of the TPM1 gene, results from an A to C substitution at nucleotide position 470. The aspartic acid at codon 157 is replaced by alanine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

HelpRecord last updated May 01, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
