De-novo "germline second hit" loss-of-heterozygosity RBP3 deletion mutation causing recessive high myopia.

Abstract excerpt

Knudson's "two hit" hypothesis, mostly associated with cancer, relates to a primary heterozygous germline mutation complemented by a somatic mutation in the second allele. When the somatic "second hit" is a deletion mutation, the heterozygosity due to the first hit is lost ("loss of heterozygosity"). As the rate of germline mutations is almost two orders of magnitude lower than that of somatic mutations, de-novo...
