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 Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_078480.3. Strenght limited to Supporting due to length of the change: 1aa.

The c.1456_1458delGAG (p.E486del) alteration, located in coding exon 12 of the PUF60 gene, results from an in-frame deletion of 3 nucleotides at positions c.1456 to c.1458. This results in the deletion of a glutamate residue at codon 486. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be deleterious by in silico analysis (Choi, 2012). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
