Genes affected

MINK1 (HGNC:17565): (misshapen like kinase 1) This gene encodes a serine/threonine kinase belonging to the germinal center kinase (GCK) family. The protein is structurally similar to the kinases that are related to NIK and may belong to a distinct subfamily of NIK-related kinases within the GCK family. Studies of the mouse homolog indicate an up-regulation of expression in the course of postnatal mouse cerebral development and activation of the cJun N-terminal kinase (JNK) and the p38 pathways.

The c.1130A>T (p.Q377L) alteration is located in exon 12 (coding exon 12) of the MINK1 gene. This alteration results from a A to T substitution at nucleotide position 1130, causing the glutamine (Q) at amino acid position 377 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
