ABSTRACT: Background
Say-Barber-Biesecker-Young-Simpson (SBBYSS) variant of Ohdo syndrome is a rare, autosomal dominant and clinically heterogenous disorder, caused by pathogenic variants in the KAT6B gene located on chromosome 10q22.2. KAT6B encodes a highly conserved histone acetyltransferase belonging to the MYST family. Currently, diseases caused by pathogenic variants in KAT6B (KAT6B-related disorders) comprise two allelic entities: SBBYSS variant of Ohdo syndrome and genitopatellar syndrome (GPS). Increase in the number of cases with overlapping GPS/SBBYSS phenotype which makes it necessary to redefine this group of phenotypes as KAT6B-related disorders or KAT6B spectrum disorders. Individuals with SBBYSS usually present with facial abnormalities, hypotonia, joint laxity, feeding probl
