Chromosome 5p Deletions

Chromosome 5p Deletion Syndrome or "Cri du Chat" (cat's cry) is a partial monosomy syndrome occurring in humans (1:15,000 to 1:50,000 live-born infants) associated with a piece of chromosome 5 is missing.

  • Vertical lines indicate the critical regions for the cry in p15.3, and for the other signs of Cri du Chat syndrome in p15.2.
  • Vertical lines in p15.1, p14 and p13 refer to clinical symptoms reported in individual families with interstitial deletions.
Clinical Features Malformations (infrequently associated)
  • high-pitched monochromatic cry
  • severe psychomotor retardation.
  • severe mental retardation.
  • microcephaly
  • broad nasal bridge
  • epicanthal folds
  • micrognathia
  • abnormal dermatoglyphics
  • cardiac
  • other neurological
  • renal abnormalities
  • preauricular tags
  • syndactyly
