September 2016 in “Journal of dermatological science” This study suggested that differences in hair follicle development, indicated by the frequency of underdeveloped hairs, significantly contribute to the variation in hair loss severity among Japanese individuals with the LIPH c.736T>A mutation.
September 2016 in “Journal of Dermatological Science” This study identified that in Japanese patients with autosomal recessive woolly hair/hypotrichosis, the c.736T > A LIPH mutation is associated with a mild phenotype, while the c.742C > A mutation may lead to severe baldness.
July 2025 in “Frontiers in Medicine” This study identified compound heterozygous mutations, c.1101del and c.736 T > A, in the LIPH gene responsible for causing autosomal recessive woolly hair in a child, with c.1101del being a novel frameshift mutation.
May 2024 in “Frontiers in medicine” In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.
December 2025 in “Frontiers in Medicine” This review details the global mutation patterns of genes associated with autosomal recessive woolly hair/hypotrichosis and highlights potential, yet unproven, treatments like minoxidil and regenerative therapies, reporting no new clinical results.
