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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.96).

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000046 (7/152148) while in subpopulation EAS AF = 0.00136 (7/5156). AF 95% confidence interval is 0.000636. There are 0 homozygotes in GnomAd4. There are 5 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 7 AD gene.
