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. [provided by RefSeq, Mar 2010]

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

ACMG classification

Our verdict: Benign. The variant received -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.050423443).
• BP6: Variant 2-218344505-G-A is Benign according to our data. Variant chr2-218344505-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 536504.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High AC in GnomAd4 at 72 AD gene.
