GLK coding, GLK variant coding that is a reverse sequence on chromosome 2.
Cohort #1, SLE, n=101 (24 patients with sporadic SLE and 77 patients with SLE from 62 families); non-SLE, n=163 (6 healthy controls and 157 family members without SLE from 62 families).
Cohort #2, SLE, n=80 (patients with sporadic SLE); healthy control, n=87 (non-familial healthy controls).
Allele frequencies were calculated using unrelated patients and controls; if from individual families, only one patient with SLE and one member without SLE from each family are included.
‘F’ denotes family member in Cohort #1; ‘S’ denotes patient with sporadic SLE in Cohort #1; ‘B’ indicates patient with sporadic SLE in Cohort #2.
*Single nucleotide variants.
†One male family member without SLE control (F52-02) from Cohort #1 harboured this variant.
‡One male non-familial healthy control from Cohort #2 harboured this variant.
