Title: Psoriasis Susceptibility 1 Candidate 1 (PSORS1C1) Polymorphism is Associated with Autoimmune Thyroid Disease in a Chinese Han Population.
The results of this study confirms the minor allele PSORS1C1 is positively associated with allopurinol-induced drug hypersensitivity.
Title: The minor alleles HCP5 rs3099844 A and PSORS1C1 rs3131003 G are associated with allopurinol-induced severe cutaneous adverse reactions in Han Chinese: a multicentre retrospective case-control clinical study.
results show, for the first time, the male-only associations of the PSORS1C3 gene with psoriasis risk and of the PSORS1C1/CDSN gene with severity of disease. However, the age dependent associations need to be validated in larger sample sizes as well as in other populations.
Title: HLA-C*06:02-independent, gender-related association of PSORS1C3 and PSORS1C1/CDSN single-nucleotide polymorphisms with risk and severity of psoriasis.
Patients carrying PSORS1C1 variant allele rs2233945 did not reach low disease activity at 6 months in both the whole RA group and Etanercept treated patients.
Title: Polymorphisms in STAT4, PTPN2, PSORS1C1 and TRAF3IP2 Genes Are Associated with the Response to TNF Inhibitors in Patients with Rheumatoid Arthritis.
ACPA were associated significantly with rs7574865 in STAT-4. The SNP rs2233945 in the PSORS1C1 gene was protective regarding the presence of bone erosions, while rs2542151 in PTPN2 gene was associated with joint damage.
Title: Polymorphisms in STAT-4, IL-10, PSORS1C1, PTPN2 and MIR146A genes are associated differently with prognostic factors in Italian patients affected by rheumatoid arthritis.
The association has been found between PSORS1C1 SNPs and asthma in Hispanic Americans.
Title: Genome-wide association study and admixture mapping identify different asthma-associated loci in Latinos: the Genes-environments & Admixture in Latino Americans study.
PSORS1C1/CDSN gene may play a pathogenic role in ankylosing spondylitis
Title: PSORS1C1/CDSN is associated with ankylosing spondylitis.
this study demonstrates that SNPs in the PSORS1C1-encoding gene have a strong association with RA.
Title: PSORS1C1 may be involved in rheumatoid arthritis.
Report PCR-RFLP genotyping assay for PSORS1C1 which is in linkage disequilibrium with HLA-B*58:01 and may be marker for allopurinol-related Stevens-Johnson syndrome/toxic epidermal necrolysis in Japanese.
Title: Development of a rapid and inexpensive assay for detecting a surrogate genetic polymorphism of HLA-B*58:01: a partially predictive but useful biomarker for allopurinol-related Stevens-Johnson syndrome/toxic epidermal necrolysis in Japanese.
PSORS1C1 comparison showed association with the complete set of systemic sclerosis patients and all the subsets except for the anti-centromere-positive patients but, the association was dependent on different HLA class II alleles.
Title: Confirmation of TNIP1 but not RHOB and PSORS1C1 as systemic sclerosis risk factors in a large independent replication study.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
