Hypothesis

Is CHD5 a major melanoma susceptibility gene in families linked to 1p36?

Conclusion

There is no evidence to support CHD5 as a major melanoma susceptibility gene among the eight CMM/DN families screened.

Supporting Evidence

  • Eight unrelated CMM/DN families were screened for CHD5 mutations.
  • Single nucleotide polymorphisms were found, but none co-segregated with the disease.
  • The I1117M variant was inherited from an unaffected parent.

Takeaway

The study looked for mutations in a gene called CHD5 in families with a history of melanoma, but they didn't find any that could explain the disease.

Methodology

Sequencing of CHD5 coding exons and intron-exon boundaries in affected and unaffected individuals from eight CMM/DN families.

Limitations

Small sample size and limited to coding regions and flanking splice sites.

Participant Demographics

All study subjects are of Caucasian descent.
