Аннотация
BACKGROUND: We examined an 18-month-old girl with typical clinical features of X-linked dominant chondrodysplasia punctata (CDPX2) with decreased activity of dihydroxyacetone phosphate acyltransferase (DHAP-AT), previously reported in CDPX2. On the other hand, steroid sulfatase, whose activity is deficient or decreased in X-linked ichthyosis and X-linked recessive chondrodysplasia punctata, has been reported to be normal in CDPX2, although all of these diseases have ichthyotic skin changes.
OBJECTIVE: We measured the activity of DHAP-AT and steroid sulfatase of the patients fibroblasts to confirm the DHAP-AT abnormality in CDPX2.
RESULTS: The DHAP-AT activity was remarkably reduced, but steroid sulfatase activity was within normal levels when compared with those of 2 healthy controls.
CONCLUSION: The abnormal metabolism in plasmalogen synthesis in CDPX2 was confirmed. It is, however, unknown how the decreased DHAP-AT activity is related to the skin changes.
