Genes affected

PRKRA (HGNC:9438): (protein activator of interferon induced protein kinase EIF2AK2) This gene encodes a protein kinase activated by double-stranded RNA which mediates the effects of interferon in response to viral infection. Mutations in this gene have been associated with dystonia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2008]

CHROMR (HGNC:54059): (cholesterol induced regulator of metabolism RNA)

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 2-178431654-ACAAT-A is Benign according to our data. Variant chr2-178431654-ACAAT-A is described in ClinVar as [Benign]. Clinvar id is 332612.Status of the report is criteria_provided_single_submitter, 1 stars.
