Genes affected

PNKD (HGNC:9153): (PNKD metallo-beta-lactamase domain containing) This gene is thought to play a role in the regulation of myofibrillogenesis. Mutations in this gene have been associated with the movement disorder paroxysmal non-kinesigenic dyskinesia. Alternative splicing results in multiple transcript variants.

CATIP-AS2 (HGNC:41079): (CATIP antisense RNA 2)

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.28).
• BP6: Variant 2-218339810-C-T is Benign according to our data. Variant chr2-218339810-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 1141249.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-1.31 with no splicing effect.
• BS2: High AC in GnomAd4 at 5 AD gene.
