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.

Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change replaces valine with leucine at codon 183 of the PDLIM3 protein (p.Val183Leu). The valine residue is highly conserved and there is a small physicochemical difference between valine and leucine. This variant is present in population databases (rs765318874, ExAC 0.01%) but has not been reported in the literature in individuals with a PDLIM3-related disease. -
