Oculofaciocardiodental syndrome is caused by variants in the BCL6 corepressor (BCOR) gene. We identified a novel heterozygous frameshift variant, NM_001123385.2(BCOR):c.2326del, that arose de novo in a Japanese girl with characteristic facial features, congenital heart disease, bilateral syndactyly of toes 2 and 3, congenital cataracts, dental abnormalities, and mild intellectual disability. Reports ofBCORvariants are rare, and further case accumulation is warranted.
