Nine of these were novel, with six missense (L89S, R117G, R190C, A342D, S376P, Q396P), one nonsense (S102X), one insertion (111insA), and one splice site (138+1G&gt;C) mutation. Four unrelated families had the R58X mutation and five unrelated families the R190H mutation. Of families with HLRCC, 62% (13\/21) had renal cancer and 76% (16\/21) cutaneous leiomyomas. Of women\n                    <jats:italic>FH<\/jats:italic>\n                    mutation carriers from 16 families, 100% (22\/22) had uterine fibroids.
