SLC26A4 and hypothyroidism: Only a handful of patients with SLC26A4 mutations and metabolic alkalosis have been reported in the literature including a 46-year-old Caucasian female with sensorineural deafness and hypothyroidism (Cl−: 86 mmol/l, K+:1.4 mmol/l, HCO3−: 45 mmol/l), a child following thiazide therapy (potassium 1.7, chloride 70, sodium 129, HCO3 43.8, base excess + 17.8 mmol/l, pH 7.52), and another 46-year-old woman with sensorineural deafness, hypothyroidism, and profoundly low potassium levels (K+:1.4 mmol/l, HCO3−: 45 mmol/l) [16, 36, 37].
