Trisomy 22 mosaicism with normal blood chromosomes. Case report with literature review
Abstract
A female infant with growth failure, microcephaly, hypertelorism, epicanthal folds, preauricular pit, congenital heart defect, hypotonia, and delayed development is reported. Trisomy 22 mosaicism (46,XX/47,XX,+22) was found in cultured skin fibroblasts but not in blood lymphocytes. Trisomy restricted to skin fibroblasts is uncommon.
