C0282577
•
Disease or Syndrome

SNOMED CT: Carbohydrate deficiency glycoprotein syndrome (238049009); Carbohydrate deficient glycoprotein syndrome (238049009); Carbohydrate-deficient glycoprotein syndrome (238049009); CDG - Carbohydrate-deficient glycoprotein syndrome (238049009); Congenital disorder of glycosylation (238049009)
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
•Concept ID:
C0441748
•
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
X-linked recessive inheritance
MedGen UID:
375779
•Concept ID:
C1845977
•
Finding
Source: Orphanet
A mode of inheritance that is observed for recessive traits related to a gene encoded on the X chromosome. In the context of medical genetics, X-linked recessive disorders manifest in males (who have one copy of the X chromosome and are thus hemizygotes), but generally not in female heterozygotes who have one mutant and one normal allele.

Definition

A fast growing group of inborn errors of metabolism characterized by defective activity of enzymes that participate in glycosylation (modification of proteins and other macromolecules by adding and processing of oligosaccharide side chains). This group is comprised of phenotypically diverse disorders affecting multiple systems including the central nervous system, muscle function, immunity, endocrine system, and coagulation. The numerous entities in this group are subdivided, based on the synthetic pathway affected, into disorder of protein N-glycosylation, disorder of protein O-glycosylation, disorder of multiple glycosylation, and disorder of glycosphingolipid and glycosylphosphatidylinositol anchor glycosylation. [from ORDO]
