Clinical overlap between Cowden disease and Bannayan-Riley-Ruvalcaba syndrome has rarely been described and identical germline mutations in the PTEN gene have been demonstrated in a few families with Cowden disease and some cases of Bannayan-Riley-Ruvalcaba syndrome. We report on a mother with Cowden disease and a son with Bannayan-Riley-Ruvalcaba syndrome. Mutation analysis of the PTEN gene demonstrated a heterozygous nonsense mutation R130X in both individuals. This might suggest that Cowden disease and Bannayan-Riley-Ruvalcaba syndrome are one causal entity.
考登病（Cowden disease）与班纳扬-莱利-鲁瓦尔卡瓦综合征（Bannayan-Riley-Ruvalcaba syndrome）之间的临床重叠情况鲜有报道，并且在一些考登病家族和部分班纳扬-莱利-鲁瓦尔卡瓦综合征病例中已证实PTEN基因存在相同的胚系突变。我们报告了一位患有考登病的母亲和一个患有班纳扬-莱利-鲁瓦尔卡瓦综合征的儿子。PTEN基因的突变分析显示两人均存在杂合性无义突变R130X。这可能表明考登病和班纳扬-莱利-鲁瓦尔卡瓦综合征是同一病因实体。
