Entry Name Chromosome 1q21.1 duplication syndrome
Description Chromosome region 1q21.1 contains extensive and complex low-copy repeats, and copy number variants are associated with highly variable phenotypes. Individuals with 1q21.1 deletions or duplications exhibit consistent deficits on motor and cognitive functioning and abnormalities in head circumference. Increased prevalence of macrocephaly is observed in the duplication carriers.
