PARP1 and lung cancer: A recent study in an Asian population constructed haplotypes using SNPs from PARP1 coding regions [Asp81Asp, C801T in exon 2; Alal88Thr, G721A in exon 4; Ala284Ala, C1011T in exon 7; His613Glu, C1998G in exon 13; Val762Ala, T2444C in exon 17; and Cys908Thr, G2882A in exon 20], and tested for association with lung cancer [22].
