Disease characteristics

Excerpted from the GeneReview: NGLY1-Related Congenital Disorder of Deglycosylation
Individuals with NGLY1-related congenital disorder of deglycosylation (NGLY1-CDDG) typically display a clinical tetrad of developmental delay / intellectual disability in the mild to profound range, hypo- or alacrima, elevated liver transaminases that may spontaneously resolve in childhood, and a complex hyperkinetic movement disorder that can include choreiform, athetoid, dystonic, myoclonic, action tremor, and dysmetric movements. About half of affected individuals will develop clinical seizures. Other findings may include obstructive and/or central sleep apnea, oral motor defects that affect feeding ability, auditory neuropathy, constipation, scoliosis, and peripheral neuropathy. [from GeneReviews]

Additional description

From MedlinePlus Genetics
NGLY1-congenital disorder of deglycosylation (NGLY1-CDDG) is an inherited condition that affects many parts of the body. The severity of the signs and symptoms varies widely among people with the condition.

Individuals with NGLY1-CDDG typically develop features of the condition during infancy. They often have delayed development of speech and motor skills, such as sitting and walking, and weak muscle tone (hypotonia). Many affected individuals have movement abnormalities, such as uncontrolled movements of the limbs (choreoathetosis), and some develop seizures that are difficult to treat. Individuals with NGLY1-CDDG may also have problems with liver function. Some affected individuals have eye abnormalities, including degeneration of the nerves that carry information from the eyes to the brain (optic atrophy) and changes in the light-sensing tissue at the back of the eye (the retina). A reduction or absence of tears (hypolacrima or alacrima) is a common feature of NGLY1-CDDG.  https://medlineplus.gov/genetics/condition/ngly1-congenital-disorder-of-deglycosylation
