Loss-of-function mutations of AVPR2 and L1CAM result in nephrogenic diabetes insipidus (NDI) and L1 syndrome. These diseases are inherited in an X-linked recessive manner. Females with heterozygous variants can be affected owing to skewed X-chromosome inactivation (XCI). A 3-year-old girl with normal development was presented with polydipsia and polyuria, and diagnosed of NDI through an improper response to water...
