Green List (high evidence)

Variants in this gene induce a significant GDP-mannose overload, which may affect protein glycosylation.

PMID: 24035193;
- 13 affecteds from 9 families
- GDP-mannose levels were shown to be increased in 2 of the affecteds

PMID: 28574218;
- 2 sisters with achalasia, alacrima, hypohydrosis, apparent intellectual disability, seizures, microcephaly, esotropia, and craniofacial dysmorphism homozygous for c.853+1G>A.
- Loss of GMPPA protein leading to increased levels of GDP-mannose were demonstrated
