Congenital bile acid synthesis defect 4(CBAS4)

MedGen UID:
388039
Concept ID:
C1858328
Disease or Syndrome
Synonyms: CBAS4; Cholestasis, intrahepatic, with defective conversion of; CHOLESTASIS, INTRAHEPATIC, WITH DEFECTIVE CONVERSION OF TRIHYDROXYCOPROSTANIC ACID TO CHOLIC ACID; Trihydroxycoprostanic acid in bile; Trihydroxycoprostanic acid to cholic acid
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): AMACR (5p13.2)

Definition

Congenital bile acid synthesis defect type 4 (BAS defect type 4) is an anomaly of bile acid synthesis (see this term) characterized by mild cholestatic liver disease, fat malabsorption and/or neurological disease. [from ORDO]

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.
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.
Hepatomegaly
MedGen UID:
42428
Concept ID:
C0019209
Finding
Abnormally increased size of the liver.
Giant cell hepatitis
MedGen UID:
45030
Concept ID:
C0027613
Disease or Syndrome
Chronic hepatitis characterized by parenchymal inflammation with formation of large multinucleated hepatocytes in response to a variety of insults to the liver.
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.
Fat malabsorption
MedGen UID:
108215
Concept ID:
C0554103
Pathologic Function
Abnormality of the absorption of fat from the gastrointestinal tract.
Prolonged neonatal jaundice
MedGen UID:
347108
Concept ID:
C1859236
Finding
Neonatal jaundice refers to a yellowing of the skin and other tissues of a newborn infant as a result of increased concentrations of bilirubin in the blood. Neonatal jaundice affects over half of all newborns to some extent in the first week of life. Prolonged neonatal jaundice is said to be present if the jaundice persists for longer than 14 days in term infants and 21 days in preterm infants.
Prolonged partial thromboplastin time
MedGen UID:
66815
Concept ID:
C0240671
Finding
Increased time to coagulation in the partial thromboplastin time (PTT) test, a measure of the intrinsic and common coagulation pathways. Phospholipid, and activator, and calcium are mixed into an anticoagulated plasma sample, and the time is measured until a thrombus forms.
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
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.
Hyperbilirubinemia
MedGen UID:
86321
Concept ID:
C0311468
Finding
An increased amount of bilirubin in the blood.
Elevated circulating hepatic transaminase concentration
MedGen UID:
338525
Concept ID:
C1848701
Finding
Elevations of the levels of SGOT and SGPT in the serum. SGOT (serum glutamic oxaloacetic transaminase) and SGPT (serum glutamic pyruvic transaminase) are transaminases primarily found in the liver and heart and are released into the bloodstream as the result of liver or heart damage. SGOT and SGPT are used clinically mainly as markers of liver damage.
Decreased circulating calcifediol concentration
MedGen UID:
868662
Concept ID:
C4023064
Finding
A reduced concentration of calcifediol in the blood. Calcifediol is also known as calcidiol, 25-hydroxycholecalciferol and 25-Hydroxyvitamin D3.
Decreased serum bile acid concentration
MedGen UID:
1813049
Concept ID:
C5676648
Finding
A reduction in the concentration of bile acid in the blood.
Decreased circulating vitamin E concentration
MedGen UID:
1853278
Concept ID:
C5779643
Finding
A reduced concentration of vitamin E in the blood circulation. Vitamin E is a lipophilic vitamin that is also known as alpha-tocopherol.
