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 -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.45).
• BP6: Variant 2-178432244-G-A is Benign according to our data. Variant chr2-178432244-G-A is described in ClinVar as [Benign]. Clinvar id is 469612.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-178432244-G-A is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=0.128 with no splicing effect.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
