There was also no correlation of the TTR levels to the complete blood count indices or anemia profile, nor to any biochemical nutritional laboratory markers including acid–base status, liver function tests, and creatinine or mineral status except for chloride and sodium levels (Pearson r=−0.346, P=0.004; Pearson r=−0.238, P=0.051, respectively). The gene discussed is TTR; the disease is anemia (phenotype).
