Bile acid conjugation defect 1(BACD1)

MedGen UID:
1780260
Concept ID:
C5543203
Disease or Syndrome
Synonym: HYPERCHOLANEMIA, FAMILIAL 3
 
Gene (location): BAAT (9q31.1)
 
Monarch Initiative: MONDO:0030991
OMIM®: 619232

Definition

Familial hypercholanemia-3 (FHCA3) is an autosomal recessive metabolic disorder characterized by onset of symptoms, including jaundice and failure to thrive, in early infancy. The clinical features of the disorder result from impaired absorption of fat-soluble vitamins. Vitamin D deficiency causes rickets with variable growth deficiency, and vitamin K deficiency causes a coagulopathy with decreased production of vitamin K-dependent clotting factors. More variable features may include pruritis, anemia, hepatomegaly, and bile duct proliferation on liver biopsy. Laboratory studies show abnormally increased levels of unconjugated bile acids (summary by Setchell et al., 2013). For a discussion of genetic heterogeneity of FHCA, see FHCA1 (607748). [from OMIM]

Clinical features

From HPO
Hepatomegaly
MedGen UID:
42428
Concept ID:
C0019209
Finding
Abnormally increased size of the liver.
Jaundice
MedGen UID:
43987
Concept ID:
C0022346
Sign or Symptom
Yellow pigmentation of the skin due to bilirubin, which in turn is the result of increased bilirubin concentration in the bloodstream.
Liver failure
MedGen UID:
88444
Concept ID:
C0085605
Disease or Syndrome
A disorder characterized by the inability of the liver to metabolize chemicals in the body. Causes include cirrhosis and drug-induced hepatotoxicity. Signs and symptoms include jaundice and encephalopathy. Laboratory test results reveal abnormal plasma levels of ammonia, bilirubin, lactic dehydrogenase, and alkaline phosphatase.
Rickets
MedGen UID:
48470
Concept ID:
C0035579
Disease or Syndrome
Rickets is divided into two major categories including calcipenic and phosphopenic. Hypophosphatemia is described as a common manifestation of both categories. Hypophosphatemic rickets is the most common type of rickets that is characterized by low levels of serum phosphate, resistance to ultraviolet radiation or vitamin D intake. There are several issues involved in hypophosphatemic rickets such as calcium, vitamin D, phosphorus deficiencies. Moreover, other disorder can be associated with its occurrence such as absorption defects due to pancreatic, intestinal, gastric, and renal disorders and hepatobiliary disease. Symptoms are usually seen in childhood and can be varied in severity. Severe forms may be linked to bowing of the legs, poor bone growth, and short stature as well as joint and bone pain. Hypophosphatemic rickets are associated with renal excretion of phosphate, hypophosphatemia, and mineral defects in bones. The familial type of the disease is the most common type of rickets.
Elevated circulating aspartate aminotransferase concentration
MedGen UID:
57497
Concept ID:
C0151904
Finding
The concentration of aspartate aminotransferase (AST) in the blood circulation is above the upper limit of normal.
Elevated circulating alanine aminotransferase concentration
MedGen UID:
57740
Concept ID:
C0151905
Finding
An abnormally high concentration in the circulation of alanine aminotransferase (ALT).
Conjugated hyperbilirubinemia
MedGen UID:
82787
Concept ID:
C0268307
Disease or Syndrome
Abnormally high level of conjugated bilirubin in the blood.
