Congenital disorders of glycosylation
Gene: MAN2B2
There are two different cases reported with biallelic MAN2B2 variants and congenital disorders of glycosylation. The patient reported in PMID:31775018 with homozygous p.Asp38Asn variant presented with immune deficiency, dysmorphic facial features, coagulopathy, and severe developmental delay. Although the patient reported in PMID:35637269 with compound heterozygous variants (p.Ser147del and p.Glu790Lys) had severe developmental delay, dysmorphic facial features as in the previous case, this patient had new features including cleft palate and hypospadias with no immune deficiency.
This gene has not yet been associated with relevant phenotypes either in OMIM or in Gene2Phenotype.
