Genes affected

TNIK (HGNC:30765): (TRAF2 and NCK interacting kinase) Wnt signaling plays important roles in carcinogenesis and embryonic development. The protein encoded by this gene is a serine/threonine kinase that functions as an activator of the Wnt signaling pathway. Mutations in this gene are associated with an autosomal recessive form of cognitive disability. Alternative splicing results in multiple transcript variants encoding different isoforms.

The TNIK c.3809G>A variant is predicted to result in the amino acid substitution p.Arg1270Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0083% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-170784415-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
