Genes affected

PDLIM1 (HGNC:2067): (PDZ and LIM domain 1) This gene encodes a member of the enigma protein family. The protein contains two protein interacting domains, a PDZ domain at the amino terminal end and one to three LIM domains at the carboxyl terminal. It is a cytoplasmic protein associated with the cytoskeleton. The protein may function as an adapter to bring other LIM-interacting proteins to the cytoskeleton. Pseudogenes associated with this gene are located on chromosomes 3, 14 and 17. [provided by RefSeq, Oct 2012]

The c.332A>G (p.Q111R) alteration is located in exon 3 (coding exon 3) of the PDLIM1 gene. This alteration results from a A to G substitution at nucleotide position 332, causing the glutamine (Q) at amino acid position 111 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
