Hyphomicrobium
|
D020582 |
[A genus of rod-shaped, oval, or bean-shaped bacteria found in soil and fresh water. Polar prosthecae are present and cells reproduce by budding at the tips of the prosthecae. Cells of this genus are aerobic and grow best with one-carbon compounds. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

Hypoalbuminemia
|
D034141 |
[A condition in which albumin level in blood (SERUM ALBUMIN) is below the normal range. Hypoalbuminemia may be due to decreased hepatic albumin synthesis, increased albumin catabolism, altered albumin distribution, or albumin loss through the urine (ALBUMINURIA).

|
Hypoaldosteronism
|
D006994 |
[A selective aldosterone deficiency resulting from diminished RENIN-generated ANGIOTENSIN II, a key stimulus to aldosterone secretion. Previously, it was called type IV renal tubular acidosis.
, A congenital or acquired condition of insufficient production of ALDOSTERONE by the ADRENAL CORTEX leading to diminished aldosterone-mediated synthesis of Na(+)-K(+)-EXCHANGING ATPASE in renal tubular cells. Clinical symptoms include HYPERKALEMIA, sodium-wasting, HYPOTENSION, and sometimes metabolic ACIDOSIS.

|
Hypoalphalipoproteinemias
|
D052456 |
[Conditions with abnormally low levels of ALPHA-LIPOPROTEINS (high-density lipoproteins) in the blood. Hypoalphalipoproteinemia can be associated with mutations in genes encoding APOLIPOPROTEIN A-I; LECITHIN CHOLESTEROL ACYLTRANSFERASE; and ATP-BINDING CASSETTE TRANSPORTERS.

|
Hypobetalipoproteinemia, Familial, Apolipoprotein B
|
D052476 |
[An autosomal dominant disorder of lipid metabolism. It is caused by mutations of APOLIPOPROTEINS B, main components of CHYLOMICRONS and BETA-LIPOPROTEINS (low density lipoproteins or LDL). Features include abnormally low LDL, normal triglyceride level, and dietary fat malabsorption.

|
Hypobetalipoproteinemias
|
D006995 |
[Conditions with abnormally low levels of BETA-LIPOPROTEINS (low density lipoproteins or LDL) in the blood. It is defined as LDL values equal to or less than the 5th percentile for the population. They include the autosomal dominant form involving mutation of the APOLIPOPROTEINS B gene, and the autosomal recessive form involving mutation of the microsomal triglyceride transfer protein. All are characterized by low LDL and dietary fat malabsorption.
