- lambda 5 deficiency [DOID:0060024]
A B cell deficiency that has_material_basis_in mutations in the IGLL1 gene. Lambda 5 mutations can cause a block in B cell development at the transition between the pro-B cell and the pre-B cell stage.
- PSPH deficiency [DOID:0050724]
A serine deficiency that has_material_basis_in deficiency of phosphoserine phosphatase impeding the synthesis of L-serine.
- serine deficiency [DOID:0050721]
An amino acid metabolic disorder that has_material_basis_in defects in the biosynthesis of the amino acid L-serine.
- PHGDH deficiency [DOID:0050722]
A serine deficiency that has_material_basis_in deficiency of phosphoglycerate dehydrogenase which results in a disruption of L-serine biosynthesis.
