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.

TNIK Gene-Disease associations (from GenCC):

• intellectual disability, autosomal recessive 54

  Inheritance: AR, Unknown Classification: MODERATE, LIMITED Submitted by: Illumina, Ambry Genetics, PanelApp Australia, Labcorp Genetics (formerly Invitae)
• autosomal recessive non-syndromic intellectual disability
