J. Burn et al., CONOTRUNCAL ANOMALY FACE SYNDROME IS ASSOCIATED WITH A DELETION WITHIN CHROMOSOME-22Q11, Journal of Medical Genetics, 30(10), 1993, pp. 822-824
The conotruncal anomaly face syndrome was described in a Japanese publ
ication in 1976 and comprises dysmorphic facial appearance and outflow
tract defects of the heart. The authors subsequently noted similariti
es to Shprintzen syndrome and DiGeorge syndrome. Chromosome analysis i
n five cases did not show a deletion at high resolution, but fluoresce
nt in situ hybridisation using probe DO832 showed a deletion within ch
romosome 22q11 in all cases.
