This procedure must include comprehensive medical and family history checks, specifically for thyroid and pancreatic conditions; baseline and routine laboratory workups covering renal function (serum creatinine and eGFR), hepatic profile (ALT, AST, and bilirubin), pancreatic (lipase and amylase), and thyroid hormones (TSH, T3, and T4); glycemic parameters, including HbA1c checked in non-diabetic individuals to monitor hypoglycemia or unmask latent diabetes; and neurological and ophthalmologic check to assess neuropathy and retinopathy. The gene discussed is TG; the disease is neuropathy.
