China Tropical Medicine 2023;23(2):200-
Objective To summarize the phenotypic and genotypic characteristics of mitochondrial combined oxidative phosphorylation deficiency type 1 (COXPD1), and to improve the clinicians' awareness of this mitochondrial encephalomyopathy. Methods The clinical characteristics, physical examination, laboratory examination and other data of a child with COXPD1 were analyzed retrospectively. The diagnosis was confirmed by clinical whole exon sequencing and high-precision mitochondrial genome full-length PLUS gene detection, and the phenotype and genotype were analyzed by reviewing relevant literature. Results A one-year and five-month-old boy mainly presented with hyperlactacidemia and abnormal liver function. Clinical whole exon sequencing showed that the child had homozygous variation of c. 688G>A(p.G230S) in the GFM1 gene. Sanger sequencing verified that the variation was respectively inherited from the parents of the child (both were heterozygous) with the autosomal recessive inheritance pattern. The high-precision mitochondrial genome full-length PLUS detection also did not find pathogenic mutations related to clinical phenotypes. The child was diagnosed with COXPD1. After "cocktail" therapy and liver protection therapy, the patient's condition improved. Conclusions The phenotype of COXPD1 is complicated and variable, mainly liver type and brain type. The mutation of GFM1 gene affects mitochondrial translation system function, and early gene detection is helpful for definite diagnosis.

Objective To investigate the association of HLA DRB1 alleles with gastric carcinoma and H. pylori infection. Methods HLA DRB1 alleles polymorphism in 63 patients with gastric adenocarcinoma and 136 normal controls were tested with the polymerase chain reaction/sequence specific primer(PCR/SSP) technique. The status of H. pylori infection was determined by histology of gastric biopsy specimens and /or by ELISA. Results Both HLA DRB1 0901 and HLA DRB1 12 were positively associated, and HLA DRB1 15 was negatively associated with gastric adenocarcinoma, but no significant associations were found between patients with and without above HLA DRB1 alleles with regard to patients' age at presentation, sex ratio, tumor site (distal vs proximal), TNM staging, histological grading of tumor or status of H. pylori infection. Conclusions Our results suggest that HLA DRB1 0901, DRB1 12 and DRB1 15 are associated with gastric adenocarcinoma, but are not associated with the clinical features of gastric adenocarcinoma and the status of H. pylori infection.
