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.

The p.P228L variant (also known as c.683C>T) is located in coding exon 6 of the PDLIM3 gene. This alteration results from a C to T substitution at nucleotide position 683. The proline at codon 228 is replaced by leucine, an amino acid with similar properties.This variant was previously reported in the SNPDatabase as rs201185673. Based on data from the NHLBI Exome Sequencing Project (ESP), the T-allele has an overall frequency of approximately 0.01% (1/13,006), having not been observed in 4406 of African American alleles, and observed in 0.01% (1/8600) of European American alleles studied. This variant was not observed in the 1000 Genomes Project.This amino acid position is not conserved on sequence alignment.This variant is predicted to be benign by PolyPhen and tolerated by SIFT in silico analyses. Since supporting evidence is limited at this time, the clinical significance of p.P228L remains unclear. -
