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.305C>T (p.S102L) alteration is located in exon 5 (coding exon 5) of the ILKAP gene. This alteration results from a C to T substitution at nucleotide position 305, causing the serine (S) at amino acid position 102 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
