Telomere-telomere (end to end) fusion of chromosomes 7 and 22 with an interstitial deletion of chromosome 7p11.2-->p15.1: phenotypic consequences and possible mechanisms.

Abstract excerpt

We report a rare case of a de novo end to end fusion of chromosomes 7 and 22 in conjunction with an interstitial deletion of chromosome 7p11.2p15.1 in a newborn with congenital anomalies. The proband presented for chromosome analysis with bilateral cataracts, dysmorphic facies and distal limb abnormalities. Chromosome analysis showed a 45,XY,der(22)psu dic(22;7)(p13;p22.3)del(7)(p11.2p15.1) karyotype. This short...
