Genes affected

KAT6B (HGNC:17582): (lysine acetyltransferase 6B) The protein encoded by this gene is a histone acetyltransferase and component of the MOZ/MORF protein complex. In addition to its acetyltransferase activity, the encoded protein has transcriptional activation activity in its N-terminal end and transcriptional repression activity in its C-terminal end. This protein is necessary for RUNX2-dependent transcriptional activation and could be involved in brain development. Mutations have been found in patients with genitopatellar syndrome. A translocation of this gene and the CREBBP gene results in acute myeloid leukemias. Three transcript variants encoding different isoforms have been found for this gene.

KAT6B NM_012330.3 exon16 p.Asp1077_Glu1080del (c.3231_3242delCGAGGAGGAGGA): This variant has not been reported in the literature, but has been identified by our laboratory in 1 individual with a clinical suspicion of a RASopathy. However, this individual also carried a pathogenic variant in a different gene likely to be causative of the phenotype. This variant is not present in large control databases. This variant is present in ClinVar (Variation ID:260236). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant represents an in-frame deletion of 4 amino acids at position 1077 and is not predicted to alter the reading frame. However, the effect of this variant on the protein is unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
