Variant rs119475042 details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 7P and 4B. PM1PM5PP2PP3_ModerateBS2

The ENST00000321030.9(PRPF31):c.646G>A(p.Ala216Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000684 in 1,461,640 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A216P) has been classified as Pathogenic.

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 made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM1

In a domain Nop (size 118) in uniprot entity PRP31_HUMAN there are 30 pathogenic changes around while only 1 benign (97%) in ENST00000321030.9

PM5

Other missense variant is known to change same aminoacid residue: Variant chr19-54123867-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 4359.Status of the report is no_assertion_criteria_provided, 0 stars.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PRPF31. . Gene score misZ 3.0492 (greater than the threshold 3.09). Trascript score misZ 3.3753 (greater than threshold 3.09). GenCC has associacion of gene with retinitis pigmentosa 11, PRPF31-related retinopathy, retinitis pigmentosa.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.922

BS2

High AC in GnomAdExome4 at 10 AD gene.
