22q11.2 deletion syndrome is the most frequent microdeletion syndrome in humans and caused by hemizygote deletion on only one chromosome. Most of probands have a de novo deletion of 22q11.2, but 8-20% have inherited the 22q11.2 deletion from a parent (autosomal dominant mutation). Genotype-phenotype correlation is weak in this patient group. We aimed to present three members in the same family due to an autosomal dominant inheritance with 22q11.2 deletion and different clinical findings.
