Genes affected

FERMT2 (HGNC:15767): (FERM domain containing kindlin 2) Enables several functions, including actin binding activity; phosphatidylinositol-3,4,5-trisphosphate binding activity; and type I transforming growth factor beta receptor binding activity. Involved in several processes, including cell surface receptor signaling pathway; positive regulation of cell differentiation; and positive regulation of cellular component biogenesis. Acts upstream of or within cell adhesion and protein localization to cell junction. Located in cytosol; focal adhesion; and nucleoplasm. Is extrinsic component of cytoplasmic side of plasma membrane. Part of adherens junction and plasma membrane. Biomarker of acute myeloid leukemia. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.1381G>A (p.E461K) alteration is located in exon 12 (coding exon 11) of the FERMT2 gene. This alteration results from a G to A substitution at nucleotide position 1381, causing the glutamic acid (E) at amino acid position 461 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
