Classic galactosaemia is a severe inherited disorder that can lead to various symptoms and complications due to the inability to digest galactose. A case study reported a female patient diagnosed with classic galactosaemia in adulthood, who developed multiple complications not commonly seen in current literature.
Classic galactosaemia is the most severe type, inherited in an autosomal recessive fashion and normally detected on newborn screening. It is caused by an inability to digest galactose due to a deficiency of galactose-1-phosphate uridyltransferase (GALT), resulting in an intolerance of feeds in the neonatal period, failure to thrive, hypoglycaemia, jaundice, cataracts, hepatomegaly, vomiting, diarrhoea, developmental delay and an increased risk of Escherichia coli sepsis. The long-term sequelae of this disorder include cognitive impairment, neurological symptoms, such as ataxia, nutritional deficiencies, such as calcium and vitamin D, and gonadal dysfunction. We report here a case of a 34-year-old woman with classic galactosaemia diagnosed in adulthood, developing primary ovarian insufficiency and osteoporosis as well as primary adrenal insufficiency and chronic myeloid leukaemia, which are two associations not seen in current literature. Further studies are needed to determine if an association exists between these diseases.
