DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

EDA2R gene linked to hair loss.

Scientists found a gene in mice that causes early hearing loss.

Men are more likely to get infectious skin diseases, while women are more prone to autoimmune and pigment-related skin conditions, influenced by biological and environmental factors.

The research found genetic differences in identical twins that could explain why one twin has a disease while the other does not.

Ancient Chinese goats evolved cashmere-producing traits due to selective breeding, particularly in genes affecting hair growth.

Certain gene variants in estrogen receptors are linked to polycystic ovary syndrome, mainly affecting metabolism, in Tunisian women.

Trichoepitheliomas can be hard to distinguish from other skin conditions and often start in teenage years.

SA linked to mitochondrial issues and oxidative stress, while AGA involves disrupted hair growth genes.

The most different genetic segment between Africans and East Asians is the EDA2R/AR region, with two main types influenced by population changes and natural selection, and linked to baldness.

Faulty inflammasome activation may lead to autoimmune skin diseases and could be a target for new treatments.

PNKP is essential for keeping adult mouse progenitor cells healthy and growing normally.

The research found that people's hair proteins vary by individual and body part, with some differences between ethnic groups, which could help in forensics.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

Human mitochondrial DNA polymerase makes very few errors, crucial for preventing degenerative diseases.

Different people show different symptoms for genetic diseases because of how sensitive their bodies are to small changes in important factors.
