TP53 and sarcopenia: On the account of the proven importance and prevalence of sarcopenia and due to limited published data about the relation of TP53 polymorphisms and sarcopenia, we explored the genotype and allelic frequency of two most studied polymorphisms of codon 72 polymorphism in exon 4 (rs1042522) and Intron 3 16 bp Del/Ins (rs17878362) polymorphism and their haplotypes in sarcopenia among Iranian community-dwelling older adults.
