title: New deletion syndrome: 1q43.
abstract: A male infant showed dysmorphology of the head and face, neck, extremities, and genitalia, as well as growth and mental retardation. His G-banded karyotype was 46,XY,--1+der(1),t(1;16)(q43;q24)mat. Combined with five previously reported cases involving similar terminal deletions beginning at 1q42 or 43, we show that the homology of phenotypic characteristics permits identification of a new deletion syndrome, the first involving chromosome 1.
