Genes affected

PRICKLE2 (HGNC:20340): (prickle planar cell polarity protein 2) This gene encodes a homolog of Drosophila prickle. The exact function of this gene is not known, however, studies in mice suggest that it may be involved in seizure prevention. Mutations in this gene are associated with progressive myoclonic epilepsy type 5. [provided by RefSeq, Dec 2011]

PRICKLE2-AS1 (HGNC:):

PRICKLE2-AS1 (HGNC:40916): (PRICKLE2 antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.49).
• BP6: Variant 3-64099366-G-A is Benign according to our data. Variant chr3-64099366-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 544249.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.26 with no splicing effect.
