Assignment of the human lens fiber cell MP19 gene (LIM2) to chromosome 19q13.4, and adjacent to ETFB.
The LIM2 gene may play a major role in lens fiber cell structure or communication, and thus cataractogenesis. A human cDNA encoding the corresponding lens fiber cell intrinsic protein MP19 has been previously isolated and characterized. This cDNA had been mapped to human chromosome 19. We have independently confirmed this assignment and fine mapped it to 19q13.4. The position of the LIM2 gene appears to be within 40 kb of the electron transport flavoprotein gene (ETFB) as a cosmid containing sequences from both genes has been identified.
