title: Homozygosity for fragile site at 17p12 in a 28-year-old healthy man.
abstract: In a family two heterozygous children and a homozygous phenotypically normal father with a fragile site at 17p12 were discovered. This observation confirms the opinion that even homozygosity for this fragile site is phenotypically harmless.
