I'm going to quote myself because it seems relevant ... I wrote out a while ago how I see MLC and it's origins - and no, I don't think one can inherit it, but I do think that siblings in a household, or the children of people who have MLC are probably more at risk because of the environment ... anyway ... for your reading pleasure ...

The pre-PLCer experiences this event, and then suppresses it, never learning proper coping skills as they move forward into adulthood.
As adults we all face trials and tribulations. Childrearing, financial pressure, family issues, you name it. Lots of us live in marriages built on habit and familiarity, taking our partners and ourselves for granted. At some point (frequently after another traumatic event), ALL of us feel like we are getting older and question what we want out of life. Then we look for answers. Some transition through this without as much hardship. Many decide to escape the "harsh" reality of aging/boredom and look elsewhere for their youth to be recreated. These folks are capable of looking at their lives and making choices but until they are held accountable, they don't. And then there is the group, IMO, that are not currently capable of looking inside themselves - regardless of the boundaries and consequenses they face because those consequences are much less painful then the internal closet-cleaning required to reconcile their issues. Childhood sexual, physical and/or emotional abuse, parental alcoholism, sudden death of a loved one, abandonment, neglect ... any or many never dealt with, never counselled, which simmer into a profound depression we call a "crisis". PLCer's, IMO, can not face their current issues until they go back (often literally, via regression) and deal with the emotional devastation they felt as adolecents.
