The second human beta B2-crystallin gene is a pseudogene

Exp Eye Res. 1992 May;54(5):803-6. doi: 10.1016/0014-4835(92)90036-r.


Comparison of the partial sequences of the human beta B2-1- and beta B2-2-crystallin genes with orthologous rat or calf sequences shows that the fourth exon sequence of the human beta B2-2 gene contains a one triplet deletion and a mutated splice acceptor site. No transcripts from the beta B2-2-crystallin gene could be detected in the human lens. These data suggest that the human beta B2-2-crystallin gene is a pseudogene.
