b-­Alanine

Increased levels of β-alanine on the OMX Organic Metabolomics test by Diagnostic Solutions Laboratory may indicate:

Impaired carnosine synthesis - Carnosine is formed from β-alanine and histidine. Reduced carnosine levels can lead to accumulation of β-alanine.

Vitamin B6 deficiency - Vitamin B6 is a cofactor for the enzyme that converts β-alanine to malonic semialdehyde. Deficiency can cause β-alanine to accumulate.

Uracil dihydrogenase deficiency - This enzyme converts β-alanine to malonic semialdehyde. Its deficiency leads to β-alanine buildup.

Propionic acidemia - This organic acidemia can cause elevated β-alanine levels due to impaired breakdown of odd-chain fatty acids and some amino acids.

Folate or vitamin B12 deficiency - These nutrient deficiencies can indirectly lead to β-alanine accumulation by impairing amino acid metabolism.

The OMX test measures β-alanine levels in both urine and plasma to provide a comprehensive assessment. Elevated levels warrant further investigation into vitamin status, amino acid metabolism, and organic acidemia. Targeted nutritional support may help restore balance when β-alanine is high.
