name: hypogonadotropic hypogonadism 27 without anosmia


name: overgrowth syndrome and/or cerebral malformations due to abnormalities in MTOR pathway genes

description: A disease caused by mosaic gain-of-function (GoF) of several genes in the MTOR pathway (MTOR, PIK3CA, PIK3R2 and AKT3) are functionally the same despite significant phenotypic variability. These GoF variants result in overgrowth due to an over-activation of key genes in this pathway. The phenotypic variability is generally attributed to the mosaic fraction and affected tissue types. For example, macrocephaly is noted if the variant is identified in the brain, but non symmetric overgrowth of that limb is noted when the variant is only present in the affected limb. The pathologies of the affected tissue often reveal similar characteristics such as cellular overgrowth. However, this is not always the case especially with focal cortical dysplasia. At times the characteristics pathologies are not present in the tissue but sampling biases are an issue. FCD resections often involve a very small area and so a very small amount of tissue is available for pathology and it is not guaranteed that lesional tissue is sent. Therefore, having a single disease term which can encompass the phenotypic variability yet provide a unifying molecular diagnosis name makes sense given the common functional mechanism.

glycine N-methyltransferase deficiency

description: Glycine N-methyltransferase deficiency (GNMT deficiency) is a very rare condition characterized by persistent and isolated excess levels of methionine in the blood (hypermethioninemia). The only clinical abnormalities are mild increase of the liver size (hepatomegaly) and chronic elevation of the transaminase levels in the blood without liver disease. Methionine may also be increased in urine. However, because elevated levels of methionine in the blood itself is a risk factor for development of neurological signs and symptoms, people with GNMT deficiency can have neurological problems when methionine levelsare greater than 800μmol/L. GNMT deficiency is caused by mutations in the GNMT gene. Inheritance is autosomal recessive. Treatment is not needed in most cases.

Pauci-immune GN is histologically characterized by focal necrotizing and crescentic GN, with mild or absent glomerular staining for immunoglobulin and complement by fluorescence microscopy, which may manifest either as part of a systemic small vessel vasculitis (including microscopic polyangiitis, granulomatosis with polyangiitis and eosinophilic granulomatosis with polyangiitis), or rarely as part of renal-limited vasculitis (RLV, idiopathic crescentic GN). Immunologic classification is based on the presence or absence of circulating anti-neutrophil cytoplasmic antibodies (ANCAs), namely pauci-immune-GN with ANCA and pauci-immune GN without ANCA.
