De Barsy syndrome
Other names: Cutis laxa-corneal clouding-intellectual disability syndrome[1]
De Barsy syndrome is inherited in an autosomal recessive manner.
Usual onsetInfancy

De Barsy syndrome is a rare autosomal recessive genetic disorder. Symptoms include cutis laxa (loose hanging skin) as well as other eye, musculoskeletal, and neurological abnormalities.[2] It is usually progressive, manifesting side effects that can include clouded corneas, cataracts, short stature, dystonia, or progeria (premature aging).[3]

It was first described in 1967 by De Barsy et al. and, as of 2011, there have been 27 cases reported worldwide.[4] The genes that cause De Barsy syndrome have not been identified yet,[3] although several studies have narrowed down the symptoms' cause.[5] A study by Reversade et al. (2009) has shown that recessive mutations in PYCR1 or ALD18A1, the genetic sequences that codes for mitochondrial enzymes that synthesize L-proline, are prevalent in cases of autosomal recessive cutis laxa (ARCL), a condition very similar to De Barsy syndrome.[6] [7]A study by Leao-Teles et al. has shown that De Barsy syndrome may be related to mutations in ATP6V0A2 gene, known as ATP6V0A2-CDG by the new naming system.[5]

Alternative names for De Barsy syndrome include corneal clouding-cutis laxa-mental retardation, cutis laxa-growth deficiency syndrome, De Barsy–Moens–Diercks syndrome, and progeroid syndrome of De Barsy.[2]
