    ### Instruction:
    Is Huntington disease-like syndrome inherited ?
    ### Response:
    HDL1, HDL2, and HDL4 are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person inherits the mutation from one affected parent.  As the mutation responsible for HDL2 or HDL4 is passed down from one generation to the next, the length of the repeated DNA segment may increase.
