This study analysed the association of CRH-POMC polymorphisms with psoriasis and evaluated transcript expression of lesional psoriatic and normal skin in RNA-seq data.

Background:
Skin is a target organ and source of the corticotropin-releasing hormone–proopiomelanocortin (CRH-POMC) system, operating as a coordinator and executor of responses to stress. Environmental stress exacerbates and triggers inflammatory skin diseases through modifying the cellular components of the immune system supporting the importance of CRH-POMC system in the pathogenesis of psoriasis. The aim of this study was to analyze the association of CRH-POMC polymorphisms with psoriasis and evaluate transcript expression of lesional psoriatic and normal skin in RNA-seq data.

Methods:
Samples of 104 patients with psoriasis and 174 healthy controls were genotyped for 42 single nucleotide polymorphisms (SNPs) of CRH-POMC using Applied Biosystems SNPlex™method. The transcript quantification was performed using Salmon software v1.3.0.

Results:
The current study demonstrated the associations between melanocortin 1 receptor (MC1R) polymorphisms rs2228479, rs3212369, dopachrome tautomerase (DCT) polymorphisms rs7987802, rs2031526, rs9524501 and psoriasis in the Tatar population. Very strong association was evident for the SNP rs7987802 in the DCT gene (Pc = 5.95е-006) in psoriasis patients. Additionally, the haplotype analysis provided AT DCT (rs7992630 and rs7987802) and AGA MC1R (rs3212358, 2228479, and 885479) haplotypes significantly associated (Pc ˂0.05) with psoriasis in the Tatar population, supporting the involvement of DCT and MC1R to the psoriasis susceptibility. Moreover, MC1R-203 and DCT-201 expression levels were decreased in psoriasis lesional skin compared with healthy control skin.

Conclusions:
This study is the first to identify genetic variants of the MC1R and DCT genes significantly associated with psoriasis in Tatar population. Our results support potential roles of CRH-POMC system genes and DCT in the pathogenesis of psoriasis.

What is a Tatar-population?
I bet they are non Psoriasisclub members.

And what does this mean for the whole population.
We know that genes can play a role in familiarly Psoriasis.

The Tatars (/ˈtɑːtəz/) is an umbrella term for different Turkic ethnic groups bearing the name "Tatar"

I don't know, I didn't write it.  Big Grin

But I don't know anyone in my family that has or had psoriasis and there are/were a lot of them.
