Hypotrichosis simplex (HS) is a rare form of hereditary alopecia caused by a variety of genetic mutations. Currently, only four studies regarding LSS-related HS have been reported. In this study, we try to make a definite diagnosis in two unrelated Chinese families with three pediatric patients clinically suspected of HS. Whole-exome sequencing (WES) was performed for these two families to reveal the pathogenic mutation. WES revealed two different compound heterozygous mutations in LSS in two probands that confirmed the diagnosis, including three novel mutations. In this paper, we describe a new accompanying phenotype of teeth dysplasia in a HS patient. Moreover, we provide a review of all reported LSS mutation-related patients and infer some potential genotype-phenotype correlations for the first time. © 2020 Japanese Dermatological Association.
