Study Description

Brief Summary:

Four rare genetic diseases, xeroderma pigmentosum (XP), Cockayne syndrome (CS), the XP/CS complex and trichothiodystrophy (TTD) have defective DNA excision repair although only XP has increased cancer susceptibility. We plan to perform careful clinical examination of selected patients with XP, XP/CS, CS, or TTD and follow their clinical course. We will obtain tissue (skin, blood, hair, buccal swabs) for laboratory examination of DNA repair and for genetic analysis. We hope to be able to correlate these laboratory abnormalities with the clinical features to better understand the mechanism of cancer prevention by DNA repair. Patients will be offered counseling and education for cancer control.

We plan to perform careful clinical examination of selected patients with XP, XP/CS, CS, TTD, XP/TTD and other overlap syndromes to follow their clinical course.

Outcome Measures

Primary Outcome Measures :

Identify patients with genetic diseases [ Time Frame: Up to 3 days ]
Proportion of patients with four rare genetic diseases; xeroderma pigmentosum (XP), Cockayne syndrome (CS), the XP/CS complex and trichothiodystrophy (TTD)

Secondary Outcome Measures :

Diagnosis confirmation [ Time Frame: up to 3 days ]
-To confirm suspected cases of XP, XP/CS, CS, TTD, XP/TTD and other overlap syndrome patients-by review of clinical records, by clinical examination and by laboratory testing-To document presence (or absence) of cancers (skin, eye, tongue, or internal) in XP, XP/CS, CS, TTD, XP/TTD and other overlap syndrome patients-To document atypical clinical features or unusual environmental exposures of patients with XP, XP/CS, CS, TTD, XP/TTD and other overlap syndromes
Tissue collection [ Time Frame: up to 3 days ]
obtain tissue (skin, blood, hair or buccal cells) from XP, XP/CS, CS, TTD, XP/TTD and other overlap syndromes patients, their first-degree relatives and healthy volunteers for establishment of cell cultures and for examination of DNA repair and genetic analysis
identify molecular defects [ Time Frame: up to 3 days ]
identify molecular defects in the DNA repair or other genes in cells from patients with XP, XP/CS, CS, TTD, XP/TTD and other overlap syndromes and to attempt to correlate the defects with the clinical features
overall survival [ Time Frame: yearly ]
follow the clinical course of selected patients with XP, CS, XP/CS, TTD, XP/TTD and other

Sampling Method:	Non-Probability Sample

Study Population

Patients will be sought by contacting professional organizations (such as the American Academy of Dermatology-XP Task Force), lay support groups (such as the XP Society and the Share and Care CS Support Network) or by direct referral.@@@Healthy volunteers or NIH staff will be recruited through the Program for Healthy Volunteers (CRVP@mail.cc.nih.gov), through the Patient Recruitment and Public Liaison Office (prpl@mail.cc.nih.gov), or as a self-referral through the clinicaltrials.gov web site (http://clinicaltrials.gov). Healthy volunteers may also be approached by a member of the LCBG, NCI regarding interest in participating on this protocol.

Criteria

INCLUSION CRITERIA:
On referral, subjects will be considered for inclusion in the study:

If they have clinical documentation of typical features of XP, XP/CS, CS or TTD, XP/TTD or other overlap syndromes or

If they have laboratory documentation of defective DNA repair or

If they have some suggestive clinical features and are willing to participate in the study or

if they are first degree relatives or other family members of patients with XP, XP/CS, CS, TTD, XP/TTD or other overlap syndromes

if they are healthy volunteers of age 1 year and above (including NIH employees) willing to donate blood, skin, buccal cells, or hair. Healthy volunteer children will not have skin biopsies performed if they are age 12 years or younger.

-Patients or legally authorized representatives must provide informed consent.

EXCLUSION CRITERIA:

Inability or unwillingness to provide tissue (skin, blood, buccal cells or hair) for laboratory studies.

positive pregnancy test in healthy volunteers
