Genes affected

ANKK1 (HGNC:21027): (ankyrin repeat and kinase domain containing 1) The protein encoded by this gene belongs to the Ser/Thr protein kinase family, and protein kinase superfamily involved in signal transduction pathways. This gene is closely linked to DRD2 gene (GeneID:1813) on chr 11, and a well studied restriction fragment length polymorphism (RFLP) designated TaqIA, was originally associated with the DRD2 gene, however, later was determined to be located in exon 8 of ANKK1 gene (PMIDs: 18621654, 15146457), where it causes a nonconservative amino acid substitution. It is not clear if this gene plays any role in neuropsychiatric disorders previously associated with Taq1A RFLP. [provided by RefSeq, Sep 2009]

The c.227A>G (p.K76R) alteration is located in exon 2 (coding exon 2) of the ANKK1 gene. This alteration results from a A to G substitution at nucleotide position 227, causing the lysine (K) at amino acid position 76 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
