Genes affected

PDLIM5 (HGNC:17468): (PDZ and LIM domain 5) This gene encodes a member of a family of proteins that possess a 100-amino acid PDZ domain at the N terminus and one to three LIM domains at the C-terminus. This family member functions as a scaffold protein that tethers protein kinases to the Z-disk in striated muscles. It is thought to function in cardiomyocyte expansion and in restraining postsynaptic growth of excitatory synapses. Alternative splicing of this gene results in multiple transcript variants.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32045567).

The c.767A>G (p.H256R) alteration is located in exon 6 (coding exon 5) of the PDLIM5 gene. This alteration results from a A to G substitution at nucleotide position 767, causing the histidine (H) at amino acid position 256 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
