Congenital Analbuminemia in a Korean Male Diagnosed with Single Nucleotide Polymorphism in the ALB Gene: The First Case Reported in Korea

Abstract

Congenital analbuminemia (CAA) is an autosomal recessive disease characterized by extremely low serum levels of albumin. CAA is caused by various homozygous or heterozygous mutations of the ALB gene. Patients often exhibit no clinical symptoms, aside from rare accompanying conditions, such as fatigue, ankle edema, and hypotension. This case report describes the case of a 28-year-old asymptomatic Korean male referred to our center with hypocalcemia, vitamin D deficiency, and hypoalbuminemia who was diagnosed with CAA. To determine the cause of hypoalbuminemia in the patient, laboratory tests, radiological examination, and DNA sequencing were performed. The patient was confirmed to not exhibit any other clinical conditions that can induce hypoalbuminemia and was diagnosed with CAA using DNA sequencing. The present case of CAA is the first to be reported in Korea.

Cronkhite–Canada syndrome: report of a rare case and review of the literature

“…Clinical manifestations suggest that hypoalbuminemia is not associated with liver or renal dysfunction. 13,14 Our patient exhibited substantial hypoalbuminemia (serum albumin, 21.8 g/L); her urinary albumin level was also high (537 mg/L). She exhibited multiple polyps in the gastrointestinal tract (up to 1.5 cm).…”
