A uncommon inflammatory condition called morphea causes fibrosis in the skin and subcutaneous tissue. The key stages in the pathophysiology are vascular damage, immunological response, and fibrosis. Numerous research have examined the relationships between the immune system, fibrosis, and vitamin D, but the exact pathogenetic pathways of morphea remain poorly understood. The purpose of this study was to investigate serum 25(OH)D levels and the ApaI (rs7975232) and TaqI (rs731236) polymorphisms of the vitamin D receptor (VDR) in morphea patients. There were 48 age- and sex-matched controls and 41 morphea patients total. VDR polymorphisms were found using PCR tests and gel electrophoresis, and serum 25(OH)D levels were determined using liquid chromatography combined with tandem mass spectrometry (LC–MS/MS). The patient group consisted of 37 females (90.2%) and 4 males (9.8%). The patients' mean age was 38.68 ± 17.54 years. In terms of VDR ApaI and TaqI polymorphisms, there was no discernible difference between the patient and control groups. TaqI polymorphism heterozygosity was discovered in all patients with progressive disease, and this finding was statistically significant (p = 0.012). Patients’ mean serum 25(OH)D levels were 16.98 ± 11.55 ng/mL, while those in the control group were 18.02 ± 14.30 ng/mL. VDR polymorphisms, vitamin D levels, disease subtype, age of onset, and responsiveness to treatment did not significantly correlate. In our research, we discovered that TaqI polymorphism may be related to the severity of the disease and that the polymorphisms of the VDR ApaI and TaqI were not associated with morphea susceptibility.
