Methodology for restriction-RFLP product length

Gene	Restriction enzyme	RFLP products (bp)
A1AT Sand Z mutation	Taq1	Fragments of (157 + 22 bp) and (100 + 21 bp) were detected for the wild type M allele, a 179 bp fragment for the Z allele and a 121 bp fragment for the S allele
APEX1 gene rs1130409	FspBI	Asp/Asp: 164 bp; Asp/Glu: 164 bp, 144 bp, 20 bp; Glu/Glu: 144 bp, 20 bp
