All known cases of Nova Scotia Niemann-Pick Disease (type D) were traced to a couple born in Nova Scotia in the late 1600s. It is speculated that this disease is the result of a single mutation in one of the ancestors of Yarmouth County French Acadians. In the district where most affected children lived, the heterozygote frequency was estimated to be between 10% and 26%.
所有已知的新斯科舍尼曼-匹克病(D型)病例都可追溯到17世纪末出生在新斯科舍的一对夫妇。据推测,这种疾病是雅茅斯县法裔阿卡迪亚人一位祖先发生单一突变的结果。在大多数患病儿童居住的地区,杂合子频率估计在10%至26%之间。
