This report describes a neurometabolic disorder linked to gain-of-function variants in the ODC1 gene, characterized by developmental delay, ectodermal abnormalities, and notable facial and neuroimaging features.

This study found that hair loss in an Olmsted syndrome mouse model with a Trpv3 mutation was linked to premature keratinocyte maturation, affecting hair follicle structure and function.

This study identified a recurrent mutation in the endothelin receptor type A associated with mandibulofacial dysostosis with alopecia, and proposed a mechanism involving increased ligand affinity due to structural changes.

In this study, the researchers introduced a mutation in mice to mimic Olmsted syndrome and found that the mutation caused hair loss due to impaired keratinocyte differentiation and depletion of hair follicle stem cells.

A JAK1 variant causes hair loss, skin issues, and thyroid disease, but treatment with a specific inhibitor can help.

In this study, researchers overexpressed Lrig3 in mouse skin and observed hair loss linked to changes in skin protein profiles and signaling pathways, suggesting a potential role for Lrig3 in maintaining skin homeostasis.

This study found that over- and ectopic-expression of FoxN1 in early life negatively affected the development of thymic epithelial cells, T and B cells, and skin epithelial cells.

This study found that the combination of Stemoxydine® and Resveratrol improved hair density in women with Female Pattern Hair Loss.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

In this study, a mouse model with a PIK3CA gain-of-function mutation in Schwann cells revealed unique communication with neighboring cells and a glycolytic shift in peripheral nerves, and early alpelisib treatment significantly improved symptoms, though efficacy declined with delayed administration due to limited drug penetration.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study identified a heterozygous de novo mutation in the ODC1 gene causing a new disorder characterized by overgrowth and developmental delay, and suggests that DFMO treatment may help manage elevated ODC activity and putrescine levels.

In this study, TRPV3G568V mice exhibited periodic hair loss and immune cell infiltration in the dermis, without affecting hair follicle stem cell fate, suggesting a focus on dermal immune cells for future research.

This study developed a new method to analyze Cantú syndrome mutations in KATP channels, finding that while Kir6.1 mutations increase sensitivity to potassium channel openers, SUR2B mutations show reduced sensitivity, but both result in marked hyperpolarization compared to wild-type channels under basal conditions.

This commentary explores the role of PCSK9 as a target for drug development, underscoring that individuals with PCSK9 loss-of-function mutations experience significantly lowered LDL cholesterol levels and reduced coronary events, suggesting that full inactivation of PCSK9 is effective and safe.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This study found that the medication dyclonine has a potent inhibitory effect on the TRPV3 channel, effectively rescuing cell death and alleviating pruritus symptoms in a mouse model with gain-of-function TRPV3 mutations, suggesting potential for treating skin inflammation.

This study found that Swiss cattle exhibiting rat-tail syndrome are heterozygous for genetic variants linked to pigmentation and color dilution, likely due to Holstein introgression in the Simmental breed.

This study suggests that structural changes in the TRPV3 channel are linked to severe skin conditions like Olmsted syndrome, with differences observed between heat-activated and resting states.

This study confirms that zebrafish engineered with Cantú Syndrome mutations in ABCC9 and KCNJ8 genes exhibit gain-of-function characteristics in their cardiovascular KATP channels, similar to mammalian counterparts.

This report documents the successful use of theophylline in treating an 11-year-old girl with a rare immunodeficiency syndrome, suggesting potential in drug repurposing for primary immunodeficiency disorders and asthma.

This review discusses the expanding understanding of TRPV3's role in pain and skin pathology, while highlighting the need for further pharmacological research to fully resolve its functions.

This study found that the revised 43-item PCOSQ had better validity and reliability than the original version, although further studies are needed to assess its predictive efficacy.

This study found that women with epilepsy on carbamazepine and sodium valproate monotherapy experienced more significant weight gain but showed no difference in PCOS incidence compared to phenytoin users; elevated TSH levels were more common among those on sodium valproate.

This review explores the potential benefits of using medicinal plants as an alternative or supplementary therapy for improving reproductive and metabolic health in women with polycystic ovary syndrome, but reports no new results.

Women with epilepsy should be monitored for reproductive issues, which can be caused by epilepsy or its treatments, especially when using valproate.

This study found that metabolic adaptations in skin epithelial stem cells, specifically redox ratio recovery and glycolytic flux modulation, define competitive outcomes between wild-type and mutant cells in different oncogenic environments.

This study demonstrated that dominant mutations in mouse gasdermin A3 disrupt mitochondrial oxidative stress regulation, suggesting a gain-of-function effect on epidermal differentiation.

In this case study, a 26-year-old woman with hypothyroidism experienced significant improvements in energy, emotional balance, and physical discomfort after individualized homeopathic treatment with Kalium carbonium, demonstrating the potential benefits of a holistic approach to care.

This study found that selective deletion of PIKFyve kinase using a PF4 promoter in mice led to defective platelet lysosome biogenesis and a prothrombotic effect, with unexpected macrophage infiltration in multiple organs.
