Comparison of the Van Blitterswijk et al., and Gallagher et al., studies

study	SNP	minor allele	Ref. allele	model	Reported OR/Beta	OR/Beta Minor Allele
Risk for disease
Gallagher	rs1990622	C	T	Allelic	1.56 (table 3)	0.64 (minor allele carriers>lower risk)
Van Blitterswijk	rs3173615	G	G	Recessive	0.33 (table 1)	0.33
Age at onset
Gallagher	rs1990622	C	T	Additive	+3.47 (table 2)	−3.47 (minor allele carriers>earlier onset)
Gallagher	rs1990622	C	T	Dominant respect major allele*	–	–
Van Blitterswijk	rs3173615	G	G	Recessive respect minor allele*	−1.26 (table 3)	−1.26 (minor allele carriers>earlier onset)

Ref. Allele= reference allele.

OR= Odds ratio

^*please note that a genetic dominant model (MM+Mm vs. mm) respect to the major allele is the same as a recessive model respect to the minor allele (MM+Mm vs. mm). “M” denotes major allele and “m” minor allele
