  • Title: Macrocephaly-cutis marmorata telangiectatica congenita: report of a patient with a translocation.
    Author: Stoll C.
    Journal: Genet Couns; 2003; 14(2):173-9. PubMed ID: 12872811.
    Abstract:
    Cutis marmorata telangiectatica congenita (CMTC) is a rare cutaneous disorder. More than one half of the patients with CMTC have additional extra-cutaneous associated congenital anomalies. A subset of patients with CMTC have macrocephaly, the M-CMTC syndrome. This is a report on a patient with the M-CMTC syndrome and a de novo translocation t(2;17)(p11;p13). The etiology and pathology of the M-CMTC syndrome is unknown. Suggestions for the cause for M-CMTC include the occurrence of a new dominant mutation in a single gene, deletion of multiple contiguous genes at a level beyond the resolution of conventional karyotyping and chromosomal mosaicism. This patient did not have chromosomal mosaicism, however he had a translocation. It can be postulated that in the present patient the translocation breakpoints disrupted one or more genes entailing skin lesions but also other features: mental retardation, macrocephaly and facial dysmorphia.
