Clinical features

From HPO
4-Hydroxyphenylpyruvic aciduria
MedGen UID:
376416
Concept ID:
C1848678
Finding
Increased relative concentration of 4-hydroxyphenylpyruvic acid in the urine.
4-hydroxyphenylacetic aciduria
MedGen UID:
376417
Concept ID:
C1848680
Finding
Increased concentration of 4-hydroxyphenylacetic acid in the urine.
Congestive heart failure
MedGen UID:
9169
Concept ID:
C0018802
Disease or Syndrome
The presence of an abnormality of cardiac function that is responsible for the failure of the heart to pump blood at a rate that is commensurate with the needs of the tissues or a state in which abnormally elevated filling pressures are required for the heart to do so. Heart failure is frequently related to a defect in myocardial contraction.
Fetal growth restriction
MedGen UID:
4693
Concept ID:
C0015934
Pathologic Function
An abnormal restriction of fetal growth with fetal weight below the tenth percentile for gestational age.
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.
Abdominal distention
MedGen UID:
34
Concept ID:
C0000731
Finding
Distention of the abdomen.
Ascites
MedGen UID:
416
Concept ID:
C0003962
Disease or Syndrome
Accumulation of fluid in the peritoneal cavity.
Cholestasis
MedGen UID:
925
Concept ID:
C0008370
Disease or Syndrome
Impairment of bile flow due to obstruction in bile ducts.
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.
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.
Microvesicular hepatic steatosis
MedGen UID:
376784
Concept ID:
C1850415
Finding
A form of hepatic steatosis characterized by the presence of small, lipid-laden vesicles in the affected hepatocytes.
Lethargy
MedGen UID:
7310
Concept ID:
C0023380
Sign or Symptom
A state of disinterest, listlessness, and indifference, resulting in difficulty performing simple tasks or concentrating.
Depletion of mitochondrial DNA in muscle tissue
MedGen UID:
867163
Concept ID:
C4021521
Finding
Respiratory distress
MedGen UID:
96907
Concept ID:
C0476273
Sign or Symptom
Respiratory distress is objectively observable as the physical or emotional consequences from the experience of dyspnea. The physical presentation of respiratory distress is generally referred to as labored breathing, while the sensation of respiratory distress is called shortness of breath or dyspnea.
Hypoglycemia
MedGen UID:
6979
Concept ID:
C0020615
Disease or Syndrome
A decreased concentration of glucose in the blood.
Hypoalbuminemia
MedGen UID:
68694
Concept ID:
C0239981
Finding
Reduction in the concentration of albumin in the blood.
Conjugated hyperbilirubinemia
MedGen UID:
82787
Concept ID:
C0268307
Disease or Syndrome
Abnormally high level of conjugated bilirubin in the blood.
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.
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.
Hypertyrosinemia
MedGen UID:
742296
Concept ID:
C1879362
Disease or Syndrome
An increased concentration of tyrosine in the blood.
Hypermethioninemia

887708
Concept ID:
C4048705
Disease or Syndrome
An increased concentration of methionine in the blood.
Polyhydramnios
MedGen UID:
6936
Concept ID:
C0020224
Pathologic Function
