Genes affected

PLEK (HGNC:9070): (pleckstrin) Enables phosphatidylinositol-3,4-bisphosphate binding activity; protein homodimerization activity; and protein kinase C binding activity. Involved in several processes, including G protein-coupled receptor signaling pathway; actin cytoskeleton organization; and positive regulation of supramolecular fiber organization. Located in cytoplasm and ruffle membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.1022C>T (p.A341V) alteration is located in exon 9 (coding exon 9) of the PLEK gene. This alteration results from a C to T substitution at nucleotide position 1022, causing the alanine (A) at amino acid position 341 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
