The balance of expression of PTPN22 splice forms is significantly different in rheumatoid arthritis patients compared with controls

Table 3 Expression of PTPN22 transcripts in peripheral blood mononuclear cells for a cohort of 60 multiple sclerosis patients (cohort IV)

	Median relative quantity values
	Control group	MS Patient group	P-value^a
Cohort IV
PTPN22_v4	1.05	1.36	0.01
PTPN22-long	1.03	0.91	NS
long/v4	1.01	0.68	0.0003

All values are relative to the average expression of non-induced controls. Controls are from cohort I using the previous measurement. The same protocol for sample preparation was used as for cohort IV. ^aP-value for comparison of the patient group and control group, Mann-Whitney test. NS, not significant.
