Malnutrition can be referred to by following several different criteria, including more than 5% weight loss in three months or more than 10% in a six-month period, or a BMI less than 20 kg/m2, while albumin levels less than 35 g/L can be suggestive of malnutrition as well [8,9,10]. The gene discussed is ALB; the disease is nutritional deficiency disease.
