Genes affected

WDR97 (HGNC:26959): (WD repeat domain 97) The function and protein-coding potential of this gene is unknown. The exon combination is based on AB058778.1 for which two possible open reading frames can be predicted (with start codons at nucleotide 26 or 2614). The position of the first ORF stop codon is consistent with a prediction of nonsense-mediated decay. Given the observation of the first ORF and its length, a predicted translation of the second ORF is inconsistent with the translation leaky scanning theory. Therefore, this gene is represented as a non-protein-coding transcript. [provided by RefSeq, Oct 2008]
