Genes affected

PRPF31 (HGNC:15446): (pre-mRNA processing factor 31) This gene encodes a component of the spliceosome complex and is one of several retinitis pigmentosa-causing genes. When the gene product is added to the spliceosome complex, activation occurs.[provided by RefSeq, Jan 2009]

PRPF31-AS1 (HGNC:40700): (PRPF31 antisense RNA 1)

ACMG classification

Our verdict: Pathogenic. The variant received 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 19-54122530-CAA-C is Pathogenic according to our data. Variant chr19-54122530-CAA-C is described in ClinVar as Pathogenic. ClinVar VariationId is 1275773.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
