Early detection of chromosome 9q22.32q31.1 microdeletion and the nevoid basal cell carcinoma syndrome

Eur J Med Genet. 2009 Mar-Jun;52(2-3):145-7. doi: 10.1016/j.ejmg.2009.02.002. Epub 2009 Feb 21.

Abstract

We report on a patient with a microdeletion of chromosome region 9q22.32q31.1 including the PTCH1 gene (human homologue of the Drosophila patched 1 gene), review the findings in the reported patients with similar array CGH findings, and highlight the non nevoid basal cell carcinoma/non-Gorlin syndrome findings at an earlier age. These are macrocephaly, neonatal hypotonia, severe psychomotor retardation with markedly delayed motor milestones and speech development, epicanthic folds, a thin upper lip, a short and wide/webbed neck, pectus excavatum and (kypho)scoliosis. These features should alert the physician to an early diagnosis of the microdeletion and allow the initiation of essential clinical management hereof.
