Involvement in diseasei

Congenital disorder of glycosylation 2L (CDG2L)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions. Clinical features of CDG2L include neonatal intractable focal seizures, vomiting, loss of consciousness, intracranial bleeding due to vitamin K deficiency, and death in infancy.

Shaheen syndrome (SHNS)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn autosomal recessive form of syndromic mental retardation. Affected individuals show severe intellectual disability, hypohidrosis, dental enamel hypoplasia, and hyperkeratosis of the palms and soles. Some may develop mild microcephaly.
