A total of 341 patients with different racial background were retrieved from 60 BSCL-related studies: BSCL type I (AGPAT2) n = 83, type II (BSCL2) n = 168, type III (CAV1) n = 1, type IV (PTRF) n = 26, patients with unknown genotype n = 62, and only one patient with mutations in both BSCL2 and PTRF [16]. Here, CAV1 is linked to Berardinelli-Seip congenital lipodystrophy.
