The chromosome 9p21 region has been described to be frequently deleted in several neoplasias. The cyclin dependent kinase inhibitor 2A (CDKN2A or P16) gene was cloned in this region and identified as a tumour suppressor gene. However, much evidence indicates the existence of another tumour suppressor gene located proximal to the CDKN2A gene, which could be involved in cutaneous malignant melanoma (CMM) initiation. In the present report we have further investigated this 9p21 chromosomal region and cloned and characterised a novel gene within it (C9orf11). This gene shares no similarities to any known gene or predicted protein representing a novel human gene. Nevertheless, a putative leucine zipper pattern is located at the C-terminal end of the predicted protein, suggesting that it could dimerise. C9orf11 encodes for a protein of 294 amino acids with a predicted molecular mass of 32.8 kDa. C9orf11 is organised in eight exons that encompass a region of approx. 13 kb. Expression analysis demonstrates that C9orf11 is highly expressed in testis, although minor expression was seen in other tissues. Mutations in the C9orf11 gene were not detected in CMM families that were negative for CDKN2A mutations. Two SNPs for the C9orf11 gene have been identified, which could be used in segregation or association studies for other disorders.
