Several genes – K-Rev interaction trapped 1 (ССМ1), Malcavernin (CCM2) and Programmed cell death protein 10 (ССМ3) – have been identified as having mutations thought to be related to these lesions. These genes are located at 7q21.2 (chromosome 7 long arm), 7p13 (chromosome 7 short arm) and 3q25.2-q27 (chromosome 3 long arm) respectively. These lesions are further discussed in the Online Mendelian Inheritance in Man site – the reference numbers are OMIM 116860, OMIM 603284 and OMIM 603285 respectively.
