i just discovered from a research paper that if 2 parents have given the same mutation in the gene as in krabbe disease, then the age of onset will be the latest. there are 4 stages of onset, infant, 6mos-2 and juvenile and it can happen in adulthood at any time. if the age on one parent's mutation is adult then the baby will inherit it only when he is an adult but if both parents are the same stage, for example, infant mutation then the baby will show symptoms as an infant. so it's the latest stage takes precedence but a match assigns the onset.
