Two argentinean siblings with CDG-IX: A novel type of congenital disorder of glycosylation?
Congenital disorders of glycosylation (CDG) aregenetic diseases caused by abnormal protein and lipidglycosylation. In this chapter, we report the clinical, biochemical,and molecular findings in two siblings with anunidentified CDG (CDG-Ix). They are the first and thethird child of healthy consanguin...

Congenital disorders of glycosylation (CDG) aregenetic diseases caused by abnormal protein and lipidglycosylation. In this chapter, we report the clinical, biochemical,and molecular findings in two siblings with anunidentified CDG (CDG-Ix). They are the first and thethird child of healthy consanguineous Argentinean parents.Patient 1 is now a 11-year-old girl, and patient 2 died at theage of 4 months. Their clinical picture involved liver dysfunctionin the neonatal period, psychomotor retardation,microcephaly, seizures, axial hypotonia, feeding difficulties,and hepatomegaly. Patient 1 also developed strabismusand cataract.
