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

Our verdict: Pathogenic. The variant received 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 8-143818041-GGCTGGGCCTGCCCTATGTT-G is Pathogenic according to our data. Variant chr8-143818041-GGCTGGGCCTGCCCTATGTT-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 425573.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr8-143818041-GGCTGGGCCTGCCCTATGTT-G is described in Lovd as [Pathogenic].
