The aim of this study was to investigate the status of variants in genes including GSTM1 , GSTT1 (null/present), CT-262 (C > T) and CT-89 (A > T), glutathione peroxidase (GPx), and myeloperoxidase (MPO). The genotype studies were conducted with 200 thalassemia major (TM) patients and 200 healthy controls. Genotyping of GST gene was performed by multiplex polymerase chain reaction (PCR), whereas for CT, GPx and MPO genesvariants PCR- restriction fragment length polymorphism technique used. However, the enzyme activities were measured only in the patients group to assess the association with the genotypes. All enzyme estimations were performed by ELISA. We observed higher frequency of GSTT1 null, CT-89 (A > T), GPx1 198 (C > T) and MPO-463 (G > A) polymorphisms in TM patient than healthy controls. However, CT-262 (C > T) polymorphism was not found to be statistically significantly different between patients and controls. Our results suggest that frequency of null allele of glutathione-S-transferase is significantly high among TM patients. The other alleles CT-89 (A > T), GPx1 198 (C > T), and MPO-463 (G > A) are linked to decreased CT, GPX, and MPO enzyme activities.","PeriodicalId":16695,"journal":{"name":"Journal of pediatric genetics","volume":"11 3","pages":"198-212"},"PeriodicalIF":0.4,"publicationDate":"2021-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9385263/pdf/10-1055-s-0041-1723961.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40712728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, discrete round to oval cysts were present at the gray-white matter junctions in the second case, which were larger and appeared morphologically distinct from the VR spaces. These cysts did not elongate in any plane on imaging and were more representative of giant intramyelinic vacuoles.

Retrospective analysis of 28 children (14 males) under the age of 14 years with dRTA seen from 2010 to 2019 was reviewed, and detailed clinic records were analyzed.

NGS-based sequencing of DMD gene was done in 28 MLPA-negative cases (25 male probands with the DMD phenotype and 3 obligate carrier mothers of deceased affected male patients) and disease-causing variants were identified in 19 (67.9%) of these cases. Further molecular testing in four of the remaining nine cases revealed gene variants associated with limb girdle muscular dystrophies.
