DeSanctis–Cacchione syndrome is inherited in an autosomal recessive manner

DeSanctis–Cacchione syndrome or Xeroderma pigmentosum is a genetic disorder characterized by the skin and eye symptoms of xeroderma pigmentosum (XP) occurring in association with microcephaly, progressive mental retardation, retarded growth and sexual development, deafness, choreoathetosis, ataxia and quadriparesis. [2]

Signs and symptoms

Arm demonstrates hypochromic/ achromic, hyperchromic,lentiginous lesions

The clinical presentation of this condition is as follows:[3]

  • Ataxia
  • Conjunctivitis
  • Photosensitive skin
  • Ectropion
  • Gonadal hypoplasia
  • Hyporeflexia


In at least some case, the gene lesion involves a mutation in the CSB gene.[4]

It can be associated with ERCC6.[4]


The diagnosis of DeSanctis–Cacchione syndrome is done via the following:[3]

  • Medical exam
  • Medical history
  • Lab test
  • Genetic test


Management revolves around protection from sunlight so as to not have other complications (skin cancers).[5]
