Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM2 PM5 PP2 PP3_Strong PP5_Moderate

The NM_078480.3(PUF60):​c.1472G>A​(p.Gly491Glu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G491R) has been classified as Likely pathogenic.

Genes affected

PUF60 (HGNC:17042): (poly(U) binding splicing factor 60) This gene encodes a nucleic acid-binding protein that plays a role in a variety of nuclear processes, including pre-mRNA splicing and transcriptional regulation. The encoded protein forms a complex with the far upstream DNA element (FUSE) and FUSE-binding protein at the myelocytomatosis oncogene (MYC) promoter. This complex represses MYC transcription through the core-TFIIH basal transcription factor. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr8-143816729-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 986397.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PUF60. . Gene score misZ 4.4358 (greater than the threshold 3.09). Trascript score misZ 4.9183 (greater than threshold 3.09). GenCC has associacion of gene with 8q24.3 microdeletion syndrome, syndromic intellectual disability.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.949
• PP5: Variant 8-143816728-C-T is Pathogenic according to our data. Variant chr8-143816728-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 425566.Status of the report is criteria_provided_single_submitter, 1 stars.
