Numerous studies have demonstrated that there are correlations between sarcopenia and patients' basic characteristics, such as age [20–22, 24, 26, 27], sex [4, 12, 23, 27], liver function(serum albumin levels) [4, 22, 23], and BMI values [4, 12, 19, 22–24, 26–28]. The gene discussed is ALB; the disease is sarcopenia.
