چکیده انگلیسی


- NGS panel analysis identified MUT mutations in 48/53 patients diagnosed with mut MMA.
- 16 novel pathogenic mutations in MUT were identified.
- The mut diagnosis made by somatic cell studies was re-evaluated in 5 patients.

Mutations in the MUT gene, which encodes the mitochondrial enzyme methylmalonyl-CoA mutase, are responsible for the mut form of methylmalonic aciduria (MMA). In this study, a next generation sequencing (NGS) based gene panel was used to analyze 53 patients that had been diagnosed with mut MMA by somatic cell complementation analysis. A total of 54 different mutations in MUT were identified in 48 patients; 16 novel mutations were identified, including 1 initiation site mutation (c.2T > C [p.M1?]), 1 missense mutation (c.566A > T [p.N189I]), 2 nonsense mutations (c.129G > A [p.W43*] and c.1975C > T [p.Q659*]), 2 mutations affecting splice sites (c.753 + 3A > G and c.754-2A > G), 8 small insertions, deletions, and duplications (c.29dupT [p.L10Ffs*39], c.55dupG [p.V19Gfs*30], c.631_633delGAG [p.E211del], c.795_796insT [p.M266Yfs*7], c.1061delCinsGGA [p.S354Wfs*20], c.1065_1068dupATGG [p.S357Mfs*5], c.1181dupT [p.L394Ffs*30], c.1240delG [p.E414Kfs*17]), a large insertion (c.146_147ins279), and a large deletion involving exon 13. Phenotypic rescue and cDNA analysis were used to confirm that the c.146_147ins279 and c.631_633delGAG mutations were associated with the decreased methylmalonyl-CoA mutase function observed in the patient fibroblasts. In five patients, the NGS panel did not confirm the diagnosis made by complementation analysis. One of these patients was found to carry 2 novel mutations (c.433G > A [p.E145K] and c.511A > C [p.N171H]) in the SUCLG1 gene.
