research Two siblings with uncombable hair syndrome: A new pathogenic variant
Two siblings have a rare hair condition caused by a new genetic variant.
research Identification of Novel Mutations in Basic Hair Keratins hHb1 and hHb6 in Monilethrix: Implications for Protein Structure and Clinical Phenotype
New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.
research Ugreelig hår
A young boy's uncombable hair is due to a rare genetic condition that usually improves over time.
