RT Journal Article SR Electronic T1 Two reciprocal translocations associated with microcephaly and retardation. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 141 OP 142 DO 10.1136/jmg.14.2.141 VO 14 IS 2 A1 E F Bell A1 D Warburton YR 1977 UL http://jmg.bmj.com/content/14/2/141.abstract AB The first case is reported of a karyotype containing two apparently unrelated reciprocal translocations, involving chromosomes 1, 2, 5, and 7. It is suggested that the patient's psychomotor retardation and microcephaly may be the result of the loss of a small amount of chromosomal material accompanying these translocations.
