Many members of the cysteine, cathepsin, and MMP subfamilies are potent elastases and/or collagenases that mediate the degradation of these ECM proteins, leading to AAA expansion and rupture [97, 98].

The inheritance is autosomal recessive and the point of mutation is the gene for cathepsin C (CTCS), a lysosomal protease, which lies on chromosome (11q14-q21).16,17 In this case, genetic testing could not be performed to identify the gene mutation because of the low economic status of the guardians, but the dermatological, dental findings and paraclinical features strongly suggested the diagnosis of PLS.
