Genes affected
BRPF1 (HGNC:14255): (bromodomain and PHD finger containing 1) This gene encodes a bromodomain, PHD finger and chromo/Tudor-related Pro-Trp-Trp-Pro (PWWP) domain containing protein. The encoded protein is a component of the MOZ/MORF histone acetyltransferase complexes which function as a transcriptional regulators. This protein binds to the catalytic MYST domains of the MOZ and MORF proteins and may play a role in stimulating acetyltransferase and transcriptional activity of the complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 02, 2023 | The c.28_29delTT (p.F10Lfs*8) alteration, located in exon 2 (coding exon 1) of the BRPF1 gene, consists of a deletion of 2 nucleotides from position 28 to 29, causing a translational frameshift with a predicted alternate stop codon after 8 amino acids. The predicted stop codon occurs in the 5' end of the BRPF1 gene. Premature termination codons in the 5’ end of a gene have been reported to escape nonsense-mediated mRNA decay and/or lead to re-initiation (Rivas, 2015; Lindeboom, 2016; Rhee, 2017). Direct evidence for this alteration is unavailable; however, premature termination codons are typically deleterious in nature. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). Based on the available evidence, this alteration is classified as pathogenic. - |
