SQSTM1 and melanoma: Notably, expression of several genes related to autophagy such as SQSTM1, AMBRA1, WD repeat domain phosphoinositide-interacting 1 (WIPI-1), peroxisomal biogenesis factor 3 (PEX3) and BCL-2-associating athanogene-1 (BAG1) has been indicated as prognostic in melanoma [92,93,94,95], and single nucleotide polymorphisms (SNPs) have been found in others [96].
