I have called CNVs from exomes, in multiple members of distant cousins suffering from same disease using Conifer in different families. Then I tried to identify the region which are inherited by all the cousins. But I did not find any regions which are shared among themselves. But, if I try to look for the shared CNVs withing all the 50 samples, there exist many shared regions, the samples being from different families. Can I make any interpretation from this observation? Does the CNVs follow Mendelian inheritance?
