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.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KAT6B. . Gene score misZ 2.8874 (greater than the threshold 3.09). Trascript score misZ 4.8748 (greater than threshold 3.09). GenCC has associacion of gene with RASopathy, genitopatellar syndrome, KAT6B-related multiple congenital anomalies syndrome, blepharophimosis - intellectual disability syndrome, SBBYS type.

BP4

Computational evidence support a benign effect (MetaRNN=0.40993965).
