Cutis laxa in a patient with 1p36 deletion syndrome.

Chromosome 1p36 deletion is the most common subtelomeric deletion syndrome characterized by variable features including unique facial appearance, intellectual disability, developmental delay, cardiac defects, seizures and hypotonia. Here, we report a patient with developmental delay, dilated cardiomyopathy, seizures, hirsutism and cutis laxa who was diagnosed with 1p36 deletion syndrome by chromosome microarray analysis. This patient is the first reported case of 1p36 deletion syndrome associated with cutis laxa and our results suggest that the 1p36 region contains one or more genes relevant to cutis laxa. This case also indicates the importance of considering chromosome abnormalities (microdeletion/microduplication syndromes) in patients presenting skin disorders combined with unexplained developmental delay, intellectual disability or multiple congenital abnormalities.
