Extended phenotypes of PIEZO1-related lymphatic dysplasia caused by two novel compound heterozygous variants.

Abstract excerpt

Defects in the PIEZO1 gene cause lymphatic dysplasia in an autosomal recessive manner, mostly by loss-of-function variants. Moreover, since 2019, the role of PIEZO1 in bone formation has been established, but there have been no PIEZO1-related cases presenting definite skeletal involvement to date. A 21-year-old male with primary lymphatic dysplasia had some other distinctive clinical features, including multiple...
