ALE-HSA21

Pseudogenes have high sequence homology to protein coding genes but generally suffer from a disrupted coding sequence and an active homologous gene can be found at another locus. Sometimes these entries have an intact coding sequence or an open but truncated ORF, in which case there is other evidence used (for example genomic polyA stretches at the 3` end) to classify them as a pseudogene. Can be further classified as one of the following.
