Genes affected
PDLIM3 (HGNC:20767): (PDZ and LIM domain 3) The protein encoded by this gene contains a PDZ domain and a LIM domain, indicating that it may be involved in cytoskeletal assembly. In support of this, the encoded protein has been shown to bind the spectrin-like repeats of alpha-actinin-2 and to colocalize with alpha-actinin-2 at the Z lines of skeletal muscle. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. Aberrant alternative splicing of this gene may play a role in myotonic dystrophy.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.T57A variant (also known as c.169A>G), located in coding exon 2 of the PDLIM3 gene, results from an A to G substitution at nucleotide position 169. The threonine at codon 57 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Thr57Ala variant in PDLIM3 has not been previously reported in individuals with cardiomyopathy, but has been identified in 32/66734 European chromosomes b y the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs142951316). Computational prediction tools and conservation analysis do not pr ovide strong support for or against an impact to the protein. In summary, the cl inical significance of the p.Thr57Ala variant is uncertain. -
