Inherited metabolic disorders (IMDs ) are a rare and diverse group of metabolic conditions mainly caused by enzyme deficiencies, and in some of these, hormonal dysfunction is a relatively common complication. It may present in childhood and subsequently hormonal replacement is required throughout their life. Endocrinopathies can be a presenting symptom of an IMD in adulthood, which should be suspected when associated with multiorgan involvement (neurological, musculoskeletal or liver, etc.). A single IMD can affect any gland with hypogonadism, adrenal insufficiency, diabetes mellitus and thyroid dysfunction being the most common. In some cases, however, it is diagnosed later in their adult life as a secondary complication of previous therapies such as chemotherapy used during Haematopoietic Stem Cell Transplantation (HSCT) in childhood.
The mechanisms of endocrine dysfunction in this group of conditions are not well understood. Regardless, patients require ongoing clinical support from the endocrine, metabolic, bone metabolism and fertility specialists throughout their life.
Hormonal profiling should be part of the routine blood test panel to diagnose asymptomatic endocrine disorders with delayed manifestations. It is also worth considering screening for common hormonal dysfunction when patients exhibit atypical non-IMD related symptoms. In some adult-onset cases presenting with multiple endocrinopathies, the diagnosis of an IMD should be suspected.
Given that new therapies are in development (e.g. gene therapies, stem cell therapies, pharmacological chaperone and substrate reduction therapies), clinicians should be aware of their potential long-term effect on the endocrine system.
