Concept ID:
C0035528
Disease or Syndrome
Synonyms: Decreased circulating vitamin B2 concentration; Riboflavin deficiency
SNOMED CT: Riboflavine deficiency (20307000); Ariboflavinosis (20307000); Vitamin B2 deficiency (20307000); Riboflavin deficiency (20307000)

Definition

The concentration of vitamin B2 in the blood circulation is below the lower limit of normal. [from HPO]

Clinical features

From HPO
Dicarboxylic aciduria
MedGen UID:
343550
Concept ID:
C1856432
Finding
An increased concentration of dicarboxylic acid in the urine.
Poor suck
MedGen UID:
324693
Concept ID:
C1837142
Finding
An inadequate sucking reflex, resulting in the difficult of newborns to be breast-fed.
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.
Hypotonia
MedGen UID:
10133
Concept ID:
C0026827
Finding
Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.
Lactic acidosis
MedGen UID:
1717
Concept ID:
C0001125
Disease or Syndrome
An abnormal buildup of lactic acid in the body, leading to acidification of the blood and other bodily fluids.
Hypoglycemia
MedGen UID:
6979
Concept ID:
C0020615
Disease or Syndrome
A decreased concentration of glucose in the blood.
Hypothermia
MedGen UID:
5720
Concept ID:
C0020672
Finding
Reduced body temperature due to failed thermoregulation.
Ariboflavinosis
MedGen UID:
20573
Concept ID:
C0035528
Disease or Syndrome
The concentration of vitamin B2 in the blood circulation is below the lower limit of normal.
Metabolic acidosis
MedGen UID:
65117
Concept ID:
C0220981
Pathologic Function
Metabolic acidosis (MA) is characterized by a fall in blood pH due to a reduction of serum bicarbonate concentration. This can occur as a result of either the accumulation of acids (high anion gap MA) or the loss of bicarbonate from the gastrointestinal tract or the kidney (hyperchloremic MA). By definition, MA is not due to a respirary cause.
Elevated circulating acylcarnitine concentration
MedGen UID:
892855
Concept ID:
C4073171
Finding
Concentration of acylcarnitine in the blood circulation above the upper limit of normal.

Conditions with this feature

Ariboflavinosis
MedGen UID:
20573
Concept ID:
C0035528
Disease or Syndrome
The concentration of vitamin B2 in the blood circulation is below the lower limit of normal.
