Genes affected

CIT (HGNC:1985): (citron rho-interacting serine/threonine kinase) This gene encodes a serine/threonine-protein kinase that functions in cell division. Together with the kinesin KIF14, this protein localizes to the central spindle and midbody, and functions to promote efficient cytokinesis. This protein is involved in central nervous system development. Polymorphisms in this gene are associated with bipolar disorder and risk for schizophrenia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, CIT
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.982
• PP5: Variant 12-119857620-C-A is Pathogenic according to our data. Variant chr12-119857620-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 254134.Status of the report is no_assertion_criteria_provided, 0 stars.
