Genes affected

PKP3 (HGNC:9025): (plakophilin 3) This gene encodes a member of the arm-repeat (armadillo) and plakophilin gene families. Plakophilin proteins contain numerous armadillo repeats, localize to cell desmosomes and nuclei, and participate in linking cadherins to intermediate filaments in the cytoskeleton. This protein may act in cellular desmosome-dependent adhesion and signaling pathways. Two transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

Dec 16, 2023

The c.154G>A (p.A52T) alteration is located in exon 1 (coding exon 1) of the PKP3 gene. This alteration results from a G to A substitution at nucleotide position 154, causing the alanine (A) at amino acid position 52 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
