The Disease<strong>:<\/strong><\/h4>\n<p>A rare glycogen storage disease due to a deficiency in solute carrier family 2, facilitated glucose transporter member 2 and characterized by hepatorenal glycogen accumulation leading to severe renal tubular dysfunction and impaired glucose and galactose metabolism.<\/p>\n<h4>2. The Symptoms:<\/h4>\n<p>Onset occurs during the first few months of life with failure to thrive, polyuria (increased amount of urine), normo\/hypokalemic metabolic acidosis (leads to potassium levels \u201cK\u201d), fasting hypoglycemia and post-feeding hyperglycemia. Metabolic acidosis, hypokalemia (low K), hypophosphatemia and rickets are the consequence of severe proximal tubule dysfunction. Growth retardation and hepatosplenomegaly resulting in a protruding abdomen are evident by early childhood. Puberty can be delayed. Generalized osteoporosis can lead to fractures already during childhood. Some patients also display an abnormal fat distribution.<\/p>\n<h4>3. Actions to take in case of early diagnosis:<\/h4>\n<ul>\n<li>Infants with a positive genetic test (having 2 pathogenic variants or 2 copies of a single pathogenic variant in the<em> SLC2A2 gene<\/em>) should continue breastfeeding, <strong><em>avoid fasting.<\/em><\/strong> Early treatment is essential in preventing chronic symptoms.<\/li>\n<li>In some cases, biochemical NBS can give some clues, as increased galactose levels and biotinidase activity.<\/li>\n<li>GSD XI is a lifelong disease that requires regular evaluation by a metabolic physician and metabolic nutritionist to avoid fasting, and follow a specific diet to prevent hypoglycemia and ketosis.<\/li>\n<li>Therapy consists of replacing water and electrolytes lost through urine excretion as a result of the proximal tubule dysfunction. In addition, Vitamin D replacement is also fundamental for preventing hypophosphatemic rickets. Patients should follow a galactose-restricted diabetic diet with fructose as the main source of carbohydrate. During infancy, night feeding can be necessary in order to avoid hypoglycemia.<\/li>\n<li>The description of the first identified and treated patient reveals that renal function is preserved in adulthood despite renal tubular dysfunction and liver involvement also persisting.<\/li>\n<li>Genetic counseling is highly recommended for family planning and evaluation of at-risk family members such as siblings.<\/li>\n<\/ul>\n<h4>4.
