This review identifies 33 genetic syndromes associated with alopecia areata in children, with 67% fully genetically elucidated, and highlights their clinical features, providing insights that may aid in early prediction, diagnosis, and personalized treatments.

In this case report, folliculitis decalvans with frontal fibrosing alopecia was observed in a patient with a dark phototype, highlighting the phenotypic spectrum of folliculitis decalvans and lichen planopilaris.

In this study, researchers observed that twins with a novel de novo nonsense variant in HRAS exhibited distinctive features, including neuropsychiatric symptoms, potentially indicating a wider clinical spectrum for conditions known as RASopathies.

This study identified a splicing-site deletion in the DCAF17 gene associated with Woodhouse-Sakati syndrome in a large consanguineous pedigree, leading to typical phenotypic features.

This study identified novel LSS mutations implicated in hypotrichosis simplex with or without neurodevelopmental abnormalities, highlighting the need for careful evaluation of synonymous mutations' potential pathogenic effects.

This article discusses the use of forensic DNA phenotyping to infer physical characteristics from biological samples without a reference sample, aiding investigations but raising ethical and legal concerns.

This study identified genetic variants in the DSG4 gene associated with the autosomal recessive form of monilethrix in Chinese patients, expanding the understanding of its phenotypic spectrum and clinical features.

This case study describes the diagnosis and treatment of a Japanese girl with non-classical 21-hydroxylase deficiency, highlighting the normalization of testosterone and control of clitoromegaly after hydrocortisone therapy, but continued overgrowth issues.

In this study, researchers identified a novel genetic variant in the NR3C1 gene in a mother and her son that predicts a truncated protein, leading to glucocorticoid resistance syndrome with mild hyperandrogenic features, although no clear genotype-phenotype correlation has been established.

This study found that "early" transit amplifying cells, marked by CD271, are the first keratinocyte stem cell progenitors with distinct features, playing a significant role in early epidermal differentiation and regeneration.

This study observed that women with PCOS had significant differences in body composition and some physiological markers compared to healthy women, which may have implications for pregnancy outcomes and long-term health risks.

This study found a severe MBTPS2 gene mutation in a Japanese IFAP syndrome patient, suggesting other factors may influence the syndrome's clinical features compared to previously studied patients.

This study found that Middle Eastern patients with epidermolysis bullosa show specific correlations between their genetic variants and clinical features, which may aid in diagnosis and genetic counseling.

This paper discusses forensic DNA phenotyping, emphasizing its ability to infer visible traits from biological samples without reference samples, but notes ethical and legal concerns related to its use.

This study found a significant association between patients' sex of rearing and external genitalia in those with gonadal dysgenesis, while noting lower testosterone levels compared to controls.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This study found that alopecia areata patients have higher odds of certain comorbidities like ulcerative colitis and vitiligo, while showing lower odds for conditions like hypertension and type 2 diabetes compared to healthy controls.

This study found that anovulatory PCOS was the most common phenotypic variant among women with menstrual irregularities seeking treatment, and no cases of obese PCOS were observed.

This study found that patients with the MITF p.E318K variant are more likely to develop multiple primary melanomas and dysplastic nevi with uncommon dermoscopic patterns compared to non-carriers.

In this study, deep phenotyping of 68 patients with XPD gene defects successfully separated individuals by clinical diagnosis and survival status, potentially improving diagnosis and prognosis for xeroderma pigmentosum and trichothiodystrophy.

This research highlights significant advancements in forensic DNA phenotyping, enabling predictions of physical traits, ancestry, and age from crime scene DNA, but notes that further research and validation are needed for greater accuracy and reliability.

This study examined 162 patients and found that those with both alopecia areata and atopic diseases showed higher cases of severe alopecia in children and a tendency for combined atopic diseases. Sensitization patterns were similar between alopecia areata patients and those with atopic diseases alone.

In this study, using a mouse model, researchers found that inducing senescence in hair follicle stem cells led to hair regeneration failure and sebaceous gland enlargement, akin to androgenetic alopecia features.

This study on Qatari patients with Woodhouse-Sakati syndrome highlights the high incidence and diverse clinical presentation due to a specific genetic variant, emphasizing early diagnosis for effective management.

This study investigated a patient with spinal and bulbar muscular atrophy who had 68 CAG repeats, revealing early onset and unique symptoms not previously documented in the condition.

This study describes various clinical phenotypes associated with FOXN1 mutations, finding that affected individuals may develop different severities of immunodeficiency based on their genetic mutations.

This study found that restoring hypothalamic NPY levels in mice delayed aging-related characteristics such as fat loss, hair loss, and memory decline, suggesting that maintaining these levels could be important for counteracting aging and its effects.

This research found significant associations between gut microbiome composition and 14 out of 37 examined health conditions, suggesting that increased microbial abundance often aligns with favorable health states.

This study identified a novel G207E STING mutation causing a distinct phenotype involving alopecia, photosensitivity, and thyroid dysfunction, and suggests that common polymorphisms in TMEM173 and IFIH1 may influence disease presentation.

This review emphasizes the importance of considering race and ethnicity-specific factors in diagnosing and treating polycystic ovary syndrome (PCOS) and calls for diagnostic criteria tailored to these differences.
