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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.58G>A (p.D20N) alteration is located in exon 1 (coding exon 1) of the ANKK1 gene. This alteration results from a G to A substitution at nucleotide position 58, causing the aspartic acid (D) at amino acid position 20 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
