In this case report, researchers described a two-year-old girl with Vitamin D dependent rickets Type II, noting elevated 1,25-dihydroxyvitamin D3 and alopecia, and observed limited treatment response likely due to poor compliance.

This abstract discusses two types of hereditary vitamin D metabolism defects, VDDR I and VDDR II, and reports on their distinct characteristics and treatment responses, without presenting new clinical data.

This case study describes a 5-year-old boy with vitamin D dependent rickets type 2, motor delays, and alopecia totalis who showed improved biochemical parameters with calcium and calcitriol treatment.

This case report highlights the use of microarray analysis to identify cryptic chromosomal rearrangements in a young woman with intellectual disability and multiple congenital anomalies.

This study reports that a lower 2D:4D finger length ratio is significantly associated with higher disease activity and reduced spinal mobility in females with ankylosing spondylitis, but not in males.

This case study reported on a 3-year-old child with vitamin D-dependent rickets type II treated in the Gaza Strip, whose condition deteriorated despite vitamin D and calcium treatments, leading to recurrent chest infections, respiratory failure, and eventual death.

This article discusses various causes of rickets in children and describes VDDR-2A as a type of refractory rickets often linked to alopecia totalis in infancy, but reports no new clinical findings.

This study found that HtrA2 inactivation in mnd2 mice is associated with delayed hair cycle phases and growth retardation of adipocytes, suggesting HtrA2's role in regulating adipogenesis-related hair growth.

Farudodstat may effectively treat alopecia areata without harmful side effects.

A woman with type 2 diabetes developed alopecia areata, suggesting a link between the two autoimmune conditions.

This case report discusses the diagnostic challenges and management options for three siblings with 46, XY DSD due to type 2 5-α reductase deficiency, highlighting the genetic basis and impact on their quality of life.

In this study, 2-deoxy D-glucose did not prevent the progression of alopecia areata or promote hair regrowth in a mouse model despite its efficacy in other autoimmune conditions.

This report describes siblings with vitamin D-dependent rickets type 2, characterized by growth retardation, alopecia totalis, and low 25(OH)D3 levels, highlighting its autosomal recessive pattern and distinction from other rickets types.

This case report observed that while a 4-year-old boy with vitamin D-dependent rickets type II showed biochemical and bone improvement after vitamin D and calcium treatment, his alopecia did not improve.

This study highlights a rare case of vitamin D-dependent rickets type 2A caused by a heterozygous mutation in the vitamin D receptor gene, emphasizing the complexity of managing this condition with high-dose calcium and vitamin D therapy.

This article reviews Vitamin D-dependent rickets Type II with a focus on alopecia as a potential diagnostic clue for this rare disorder, reporting no new clinical findings.

Mutations in Far2 mice cause hair loss due to sebaceous gland issues.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

This case study reports on a rare form of vitamin D resistant rickets in a 37-year-old male, highlighting the condition's clinical features and the necessity for a thorough understanding of calcium and vitamin D metabolism in the diagnosis and management of metabolic bone diseases.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

This review discusses inherited forms of vitamin D-dependent rickets and explains their genetic and metabolic causes but reports no new clinical findings.

This study observed a strong negative association between the HLA-DQB1*0201 allele and the alopecia totalis/alopecia universalis phenotype in Caucasian individuals, indicating a potential protective role.

This paper argues that the Equality Act's definition of 'disfigurement' should include a wider range of appearance-altering conditions beyond just scarring, due to overlaps with appearance and disability concepts.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

Farudodstat may effectively treat alopecia areata without harming hair follicles.

In this case report, a 46-year-old woman initially diagnosed with 21-hydroxylase deficiency congenital adrenal hyperplasia was later identified as having 3β-HSD2 deficiency after further investigation, highlighting the need for awareness of rarer CAH forms to prevent delayed diagnosis and insufficient treatment.

This study found that individuals with heterozygous truncation-type variants in the *DSP* gene exhibit lower skin temperature and higher transepidermal water loss, with specific microscopic skin changes and pseudomonilethrix.
