Genes affected

ILK (HGNC:6040): (integrin linked kinase) This gene encodes a protein with a kinase-like domain and four ankyrin-like repeats. The encoded protein associates at the cell membrane with the cytoplasmic domain of beta integrins, where it regulates integrin-mediated signal transduction. Activity of this protein is important in the epithelial to mesenchymal transition, and over-expression of this gene is implicated in tumor growth and metastasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013]

The c.67A>T (p.T23S) alteration is located in exon 2 (coding exon 1) of the ILK gene. This alteration results from a A to T substitution at nucleotide position 67, causing the threonine (T) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
