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.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 19, 2024This sequence change creates a premature translational stop signal (p.Asn316Metfs*7) in the PCARE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PCARE are known to be pathogenic (PMID: 20398886, 24339724, 26496393). This variant is present in population databases (rs779886453, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with autosomal recessive retinitis pigmentosa (PMID: 20398884). It has also been observed to segregate with disease in related individuals. This variant is also known as c.946 del; p.Asn237MetfsX5. ClinVar contains an entry for this variant (Variation ID: 103). For these reasons, this variant has been classified as Pathogenic. -
