A patient with monosomy 1p36, atypical features and phenotypic similarities with Cantu Syndrome

We report on a 16-year-old boy with a distal 1p36 deletion with some clinical features consistent with Cantu syndrome (OMIM#239850). He also has hypercholesterolemia, type 11 diabetes, recurrent bony fractures, and non-alcoholic steatohepatitis, not previously described in either condition. The 1p36 deletion was detected in a screen of all chromosome subtelomeres using multiplex ligation-dependent probe amplification and was verified using FISH with a region-specific BAC clone. We suggest that patients suspected of having Cantu syndrome, especially those with unusual or more severe manifestations be analyzed for distal 1p36 deletions. (c) 2005 Wiley-Liss, Inc.
