A Case Associated With Abdominal Asicets Accumulation In Congenital Disorder Of Glycosylation Type Ia
Introduction: Defects in glycoprotein and glycolipid biosynthesis cause “Congenital Disorders of Glycosylation”(CDG). The incidence/prevalence of all types of CDG haven’t been just determined. Case: A 12-month-old boy was admitted due to abdominal swelling and growth-development retardation. His weight was 6kg(3P), length 68cm(3P) and head-circumference 42cm(<3P). He had prominent ears, triangular face, micrognathia and a large Mongolian spot in his gluteal region. His abdomen was distended, there were ascites and hepatosplenomegaly. Deep tendon reflexes were absent. Laboratory evaluation revealed ALT:116U/L(0-41), AST:376U/L(0-40), glucose:53mg/dl(70-110), albumin:2.8gr/dl(3.5-5), protein in urinalysis:300mg/dl(0-25). Liver biopsy was interpreted as pre-cirrhotic/cirrhotic. Cranial Magnetic Resonance Imaging was compatible with cerebral/cerebellar atrophy. The isoelectric focusing of serum transferrin disclosed a pattern of CDG-1. A compound heterozygous pathogenic mutation was detected in PMM2 gene. He was diagnosed with CDG-type1a. His healthy parents were carriers for these variants. Discussion: CDG -types presents multiple systemic symptoms, including developmental delay, hypotonia, hepatopathy, coagulopathy, ascites, pleural/pericardial effusions. We wanted to emphasize the importance of keeping in mind the broad phenotypic/genetic etiology of CDG in patients presenting with multisystem findings such as developmental delay, liver involvement.
