The disorder is most likely due to complex interactions of the hormonal axis; (1) excess TSH stimulates the FSH-receptor, (2) pituitary enlargement and hyperstimulation, (3) secondary ovarian hyperstimulation. Although it is extremely rare, it is important to recognize before the unnecess...

Survival motor neuron levels (SMN) are reduced due to mutations in the SMN1 gene. SMN function has been implicated in poor bone health. SMA is classified according to age of onset and clinical course accordingly: type 0 (prenatal), type 1 (onset <6 months, severe, never sit unsupported), type 2 (...
