GLK coding, GLK variant coding that is a reverse sequence on chromosome 2.
Association of GLK somatic variants with SLE was determined by Fisher’s exact test (two-tailed).
‘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.
Ref, DNA coding from the human genome hg19 reference.
*Variant occurs in both Cohort #1 and Cohort #2.
fs, frameship; INDEL, insertion/deletion; SLE, systemic lupus erythematosus; SNV, single nucleotide variant; UTR, untranslated region.
