Sequence (medicine)

In medicine, a sequence is a series of ordered consequences due to a single cause.^[1]

It differs from a syndrome in that seriality is more predictable: if A causes B, and B causes C, and C causes D, then D would not be seen if C is not seen. However, in less formal contexts, the term "syndrome" is sometimes used instead of sequence.

Examples include:

• oligohydramnios sequence^[2] (also known as Potter sequence)^[3]
• Pierre Robin sequence^[4]
• Poland sequence^[5]
