From the PTC patients, one had MNG and fvPTC, one MNG, lymphocytic thyroiditis and papillary pattern of PTC, one lymphocytic thyroiditis and fvPTC, and one MNG and papillary pattern of PTC.
A new germline RET mutation apparently devoid of transforming activity serendipitously discovered in a patient with atrophic autoimmune thyroiditis and primary ovarian failure.
Using the RT-PCR technique, we observed a RET/PTC rearrangement in the carcinomatous areas of patients of both families: PTC1 in family 1 and PTC3 in family 2 and a RET/PTC rearrangement in non-malignant thyroid tissue with LT in family 2.
