PTPN13 and liver disorder: Furthermore, variants of the genes GPNMB (NMB glycoprotein), LGALS3 (galectin 3), NCF2 (neutrophil cytosolic factor 2), PTPN13 (protein tyrosine phosphatase, non-receptor) type 13), RASGRP1 (RAS guanil releasing protein 1), and SLC33A1 (soil carrier family 33 member 1) would be associated with liver disease, but these results require validation [7,72].
