PG - 306-9 AB - We describe a newborn male with minor facial anomalies, pyloric stenosis, and a chromosome rearrangement that involves deletion and addition of material at 9p24.3. Routine studies showed a 46, XY, add (9) (p24) karyotype. Fluorescence in situ hybridization (FISH) with two different whole chromosome probes for chromosome 9 failed to identify whether the additional material was derived from that chromosome. FISH with single copy YAC probes from 9p24 (D9S1858, D9S1813 and D9S54) showed a more complex rearrangement involving a deletion at D9S1858 but not at D9S1813 or D9S54. Parental chromosome studies demonstrated an apparently identical 9p abnormality in the patient's mother. This report describes a familial chromosome rearrangement in an abnormal child and his normal mother and demonstrates the use and limitations of FISH in characterizing chromosomal abnormalities.
