Congenital bile acid synthesis defect 3(CBAS3)

MedGen UID:
462497
Concept ID:
C3151147
Disease or Syndrome
Synonyms: Bile Acid Synthesis Defect, Congenital, 3; Congenital Bile Acid Synthesis Defect Type 3 (CBAS3)
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).
 
Gene (location): CYP7B1 (8q12.3)
 
Monarch Initiative: MONDO:0013439

Orphanet: ORPHA79302

Definition

Congenital bile acid synthesis defect-3 (CBAS3) is an autosomal recessive disorder characterized by prolonged jaundice after birth, hepatomegaly, conjugated hyperbilirubinemia, elevations in characteristic abnormal bile acids, and progressive intrahepatic cholestasis with liver fibrosis (summary by Setchell et al., 1998 and Ueki et al., 2008). For a general phenotypic description and a discussion of genetic heterogeneity of congenital bile acid synthesis defects, see 607765. [from OMIM]

Clinical features

From HPO
Failure to thrive
MedGen UID:
746019
Concept ID:
C2315100
Disease or Syndrome
Failure to thrive (FTT) refers to a child whose physical growth is substantially below the norm.
Intrahepatic cholestasis
MedGen UID:
3042
Concept ID:
C0008372
Disease or Syndrome
Impairment of bile flow due to obstruction in the small bile ducts within the liver.
Diarrhea
MedGen UID:
8360
Concept ID:
C0011991
Sign or Symptom
Abnormally increased frequency (usually defined as three or more) loose or watery bowel movements a day.
Hematochezia
MedGen UID:
5481
Concept ID:
C0018932
Disease or Syndrome
The passage of fresh (red) blood per anus, usually in or with stools. Most rectal bleeding comes from the colon, rectum, or anus.
Hepatitis
MedGen UID:
5515
Concept ID:
C0019158
Disease or Syndrome
Inflammation of the liver.
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.
Cirrhosis of liver
MedGen UID:
7368
Concept ID:
C0023890
Disease or Syndrome
A chronic disorder of the liver in which liver tissue becomes scarred and is partially replaced by regenerative nodules and fibrotic tissue resulting in loss of liver function.
Steatorrhea
MedGen UID:
20948
Concept ID:
C0038238
Finding
Greater than normal amounts of fat in the feces. This is a result of malabsorption of lipids in the small intestine and results in frothy foul-smelling fecal matter that floats.
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.
Bile duct proliferation
MedGen UID:
120603
Concept ID:
C0267818
Disease or Syndrome
Proliferative changes of the bile ducts.
Acholic stools
MedGen UID:
436478
Concept ID:
C2675627
Finding
Clay colored stools lacking bile pigment.
Hepatic bridging fibrosis
MedGen UID:
868315
Concept ID:
C4022709
Disease or Syndrome
Hepatic fibrosis that reaches from a portal area to another portal area.
Ductal bile plugs
MedGen UID:
1815056
Concept ID:
C5706150
Finding
Bile thrombi that form an obstruction (plug) in a dilated bile duct.
Prolonged prothrombin time
MedGen UID:
208879
Concept ID:
C0853225
Finding
Increased time to coagulation in the prothrombin time test, which is a measure of the extrinsic pathway of coagulation. The results of the prothrombin time test are often expressed in terms of the International normalized ratio (INR), which is calculated as a ratio of the patient's prothrombin time (PT) to a control PT standardized for the potency of the thromboplastin reagent developed by the World Health Organization (WHO) using the formula
Splenomegaly
MedGen UID:
52469
Concept ID:
C0038002
Finding
Abnormal increased size of the spleen.
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).
Hyperbilirubinemia
MedGen UID:
86321
Concept ID:
C0311468
Finding
An increased amount of bilirubin in the blood.
Elevated circulating alkaline phosphatase concentration
MedGen UID:
727252
Concept ID:
C1314665
Finding
Abnormally increased serum levels of alkaline phosphatase activity.
