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 Gene-Disease associations (from GenCC):

• PRPF31-related retinopathy

  Inheritance: AD Classification: DEFINITIVE Submitted by: ClinGen
• retinitis pigmentosa 11

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• retinitis pigmentosa

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BS2: High AC in GnomAd4 at 13 AD gene.
