Genes affected
ILKAP (HGNC:15566): (ILK associated serine/threonine phosphatase) The protein encoded by this gene is a protein serine/threonine phosphatase of the PP2C family. This protein can interact with integrin-linked kinase (ILK/ILK1), a regulator of integrin mediated signaling, and regulate the kinase activity of ILK. Through the interaction with ILK, this protein may selectively affect the signaling process of ILK-mediated glycogen synthase kinase 3 beta (GSK3beta), and thus participate in Wnt signaling pathway.

The c.742A>T (p.S248C) alteration is located in exon 9 (coding exon 9) of the ILKAP gene. This alteration results from a A to T substitution at nucleotide position 742, causing the serine (S) at amino acid position 248 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
