Genes affected

PCARE (HGNC:34383): (photoreceptor cilium actin regulator) The protein encoded by this gene is highly expressed in photoreceptors and may associate with the primary cilium of the outer segment. The encoded protein appears to undergo post-translational lipid modification. Nonsense and missense variants of this gene appear to cause a recessive form of retinitis pigmentosa.

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. There are 107 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-29073550-T-A is Pathogenic according to our data. Variant chr2-29073550-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 191360.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr2-29073550-T-A is described in Lovd as [Pathogenic].
