Establishment of an iPSC line (BCHNDi001-A) from a patient with nicotinamide nucleotide repair system deficiency caused by biallelic NAXD mutations.

NAD(P)HX dehydratase (NAXD) gene is one of the key enzymes encoding the nicotinamide nucleotide repair system, reportedly associated with Encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy, 2 (PEBEL2). Here, we generated an induced pluripotent stem cell (iPSC) line from the dermal fibroblasts (HDFs) of a PEBEL2 patient who carried biallelic mutations, c.101_102delTA(p.

Generation of an induced pluripotent stem cell line (BCHNCi003-A) from a patient with mitochondrial pyruvate carrier deficiency caused by biallelic MPC1 mutations.

Mitochondrial pyruvate carrier deficiency (MPYCD) is a rare mitochondrial disease characterized by developmental delay, microcephaly, growth failure, increased serum lactate with a normal lactate/pyruvate ratio. Mutations in the MPC1 gene have been identified to cause MPYCD. Herein, we generated an induced pluripotent stem cell (iPSC) line from the skin fibroblasts of a patient with MPYCD, carrying biallelic mutations, c.

Thiamine pyrophosphokinase deficiency: report of two Chinese cases and a literature review.

Thiamine pyrophosphokinase (TPK) deficiency, is a rare autosomal recessive disorder of congenital metabolic dysfunction caused by variants in the gene. variants can lead to thiamine metabolic pathway obstacles, and its clinical manifestations are highly variable. We describe two cases of TPK deficiency with completely different phenotypes and different therapeutic effects, and 26 cases of previously reported were retrospectively reviewed to improve our understanding of the clinical and genetic features of the disease.
