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.

PUF60 (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 13 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
• 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 8-143817402-AG-GGGGCTGGGCCAGGGTCAA is Pathogenic according to our data. Variant chr8-143817402-AG-GGGGCTGGGCCAGGGTCAA is described in ClinVar as [Pathogenic]. Clinvar id is 520432.Status of the report is criteria_provided_single_submitter, 1 stars.
