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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

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.

PP5

Variant 8-143816542-T-C is Pathogenic according to our data. Variant chr8-143816542-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 2690939.Status of the report is no_assertion_criteria_provided, 0 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.25016668). . Strength limited to SUPPORTING due to the PP5.

The de novo heterozygous c.1658A>G, (p.Asp553Gly) variant was absent from healthy population databases (gnomAD v.3.1.2). This variant likely results in a change in the protein structure with high pathogenicity prediction tool scores. This variant was found in a patient with a phenotype that is associated to PUF60-related disorders (neurodevelopmental disorder, craniofacial dysmorphia, skeletal and skin abnormalities). A previous study has reported a similar phenotype with a missense variant located closely to this variant in a highly evolutionary conserved region (Grimes et al., 2023). -
