Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the KAT6A gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Histone acetyltransferase that acetylates lysine residues in histone H3 and histone H4 (in vitro). Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity. May act as a transcriptional coactivator for RUNX1 and RUNX2. Acetylates p53/TP53 at 'Lys-120' and 'Lys-382' and controls its transcriptional activity via association with PML. {ECO:0000269|PubMed:11742995, ECO:0000269|PubMed:11965546, ECO:0000269|PubMed:12771199, ECO:0000269|PubMed:16387653, ECO:0000269|PubMed:17925393, ECO:0000269|PubMed:23431171}.
• Disease: DISEASE: Note=Chromosomal aberrations involving KAT6A may be a cause of acute myeloid leukemias. Translocation t(8;16)(p11;p13) with CREBBP (PubMed:8782817). Translocation t(8;22)(p11;q13) with EP300 (PubMed:10824998). KAT6A-CREBBP may induce leukemia by inhibiting RUNX1-mediated transcription (PubMed:11742995). Inversion inv(8)(p11;q13) generates the KAT6A-NCOA2 oncogene, which consists of the N-terminal part of KAT6A and the C-terminal part of NCOA2/TIF2. KAT6A-NCOA2 binds to CREBBP and disrupts its function in transcription activation (PubMed:12676584). {ECO:0000269|PubMed:10824998, ECO:0000269|PubMed:11742995, ECO:0000269|PubMed:12676584, ECO:0000269|PubMed:8782817}.; DISEASE: Note=A chromosomal aberration involving KAT6A is a cause of therapy-related myelodysplastic syndrome. Translocation t(2;8)(p23;p11.2) with ASXL2 generates a KAT6A-ASXL2 fusion protein. {ECO:0000269|Ref.3}.; DISEASE: Mental retardation, autosomal dominant 32 (MRD32) [MIM:616268]: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRD32 patients manifest intellectual disability, dysmorphic facial features, delayed psychomotor development, and lack of speech. {ECO:0000269|PubMed:25728775, ECO:0000269|PubMed:25728777}.
