Activating mutations of the calcium sensing receptor (CaSR) result in autosomal dominant hypocalcaemia with hypercalciuria (ADHH), in which patients may also suffer from polyuria, polydipsia, nephrocalcinosis, renal impairment, and ectopic calcification. A mouse model, Nuf, with an activating Leu723Gln CaSR mutation has been reported to develop the features of ADHH as well as cataracts that consist of dot nuclear opacities, which have not been described in ADHH patients...

Multiple Endocrine Neoplasia type 1 (MEN1) is an autosomal dominant disorder characterised by the combined occurrence of tumours of the parathyroids, pancreas and pituitary. The MEN1 gene, which is located on chromosome 11q13 and encodes a 610 amino acid protein (menin), belongs to the class of tumour suppressors. To investigate the role of menin in tumour suppression, three different mouse models have been generated through targeted disruption of the Men1 gene. ...
