Identification of specific injury-related SNPs in high-level athletes of Arab origin: A pilot study.

Valuable insights for preventing sports injuries in athletes have been achieved through advancements in genetics. This study aimed to determine the allelic frequency of distinct single nucleotide polymorphisms (SNPs) in a group of high-level athletes of Arab origin and to explore whether any significant relationship exists between specific genotypes in the selected SNPs with the prevalence and severity of non-contact soft tissue injuries (NCSTIs) and stress fracture injuries (SFIs). A cohort of 30 Arab male adult athletes trained at the same Sports excellence Centre from various individual sports was recruited and genotyped for collagen type 5 alpha 1 () rs12722 and vitamin D receptor () rs10735810 variants. The injury data of participant athletes were collected over two training seasons and categorized according to the site and type (muscle, tendon, ligament, or stress fracture) and severity (mild, moderate, or severe). For the rs12722, the examined genotypes were not related to the NCSTIs occurrence, while for rs10735810, the CT and TT genotypes showed a prevalence for increased stress fracture injuries (RR = 7.72; 95 % CI: 1.66-35.87;  = 0.011 and RR = 9.93; 95 % CI: 2.83-34.89;  < 0.001, respectively), and increased odds for severe stress fractures (OR = 10.91, 95 % CI: 1.34-126.92,  = 0.033). This pilot study indicates a possible association between specific genotypes in the examined polymorphisms and the prevalence and severity of NCSTIs and SFIs. Given the constraints of the small sample size in the current study, additional research is required to gain a comprehensive understanding of this specific population.
