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]

Collection Method: clinical testing

The c.218C>T (p.T73M) alteration is located in exon 3 (coding exon 3) of the PLEK gene. This alteration results from a C to T substitution at nucleotide position 218, causing the threonine (T) at amino acid position 73 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
