October 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” This study identified specific germline and somatic mutations in the Phospholipase C Delta 1 gene as high-risk factors for developing hereditary trichilemmal cysts, involving a monoallelic two-hit mechanism.
March 2025 in “American Journal of Medical Genetics Part A” In this study, researchers found that mosaic PLCD1 hotspot variants, even without the recognized germline "risk allele," may be a rare but significant genetic cause of nevus trichilemmocysticus, warranting DNA testing and sensitive sequencing technologies for accurate diagnosis.
