Abstract excerpt
Heterozygous variants in ARR3, encoding cone arrestin, have emerged as a frequent cause of early-onset high myopia with a unique X-linked female-limited inheritance pattern. However, the mechanistic basis for this unusual anti-X-linked pattern is still unclear. Developmental expression profiling in mice demonstrated robust Arr3 expression in the retina from postnatal day 14 onward, with localization confined...
