Genes affected

ZCCHC13 (HGNC:31749): (zinc finger CCHC-type containing 13) This gene appears to represent an intronless retrocopy of a related multi-exon gene located on chromosome 3. However, the CDS of this intronless gene remains relatively intact, it is conserved in other mammalian species, it is known to be transcribed, and it is therefore thought to encode a functional protein. The encoded protein contains six CCHC-type zinc fingers, and is thus thought to function as a transcription factor. [provided by RefSeq, May 2010]
