Cobalamin (vitamin B12) is important in gastrulation, nervous system development and haemoglobin formation. Mutations of the ABCD4 or LMBRD1 genes can lead to cobalamin-related disorders. We report a patient with disseminated skin hyperpigmentation caused by a homozygous LMBRD1 variant. Genetic disorders of cobalamin metabolism caused by variants in the ABCD4 or LMBRD1 genes should be considered in patients presenting with cutaneous hyperpigmentation.
