3 During data collection, we came across a family belonging to Multan having Li-Fraumeni syndrome
(LFS) like characteristics (Fig.
(LFS): A diagnosis of a soft-tissue sarcoma in a patient younger than 45 who has at least two first-degree relatives with any type of cancer that was diagnosed before age 45.
The present study has evaluated endoscopic ultrasound (EUS) for screening in high-risk individuals: 13 with FAMMM families, 21 with familial pancreatic cancer, three with hereditary pancreatitis, two with Peutz-Jeghers syndrome, five with BRCA1 and BRCA2 mutations and one Li-Fraumeni syndrome
. Twentythree per cent of them showed anomalies on EUS.

, Cowden syndrome or Bannayan-Riley-Ruvalcaba syndrome or you have a first-degree relative with one of these syndromesLobular carcinoma in situ (LCIS), is not a true cancer, though it may be a marker for later cancer risk.
The 1100delC mutation in exon 10 abolishes the kinase function of CHEK2 (5) and has been reported in patients with Li-Fraumeni syndrome
in the United States and in Finnish families with a cancer phenotype suggestive of Li-Fraumeni syndrome
, including breast cancer (5).
In Li-Fraumeni syndrome
, there seems to be a family clustering of multiple malignancies, including pediatric sarcomas, breast cancer, leukemias, brain tumors, and adrenocortical carcinomas (Frebourg, Barbier, & Yan, 1995; Li & Fraumeni, 1969).
Persons with a heterozygous gene for ataxia telangectasia (53), or carrying a gene for Li-Fraumeni syndrome
(54) are examples of susceptible populations.
"Breast Cancer Gene Found," trumpeted some of the headings of news stories on the development, "Screening Test Available Soon." But at the time, scientists could only speculate that the same gene underlies cases of breast cancer in families without a history of the unusual disease, called Li-Fraumeni syndrome
(SN: 12/1/90, p.342).
Individuals who have germline mutations in TP53 have Li-Fraumeni syndrome
. Li-Fraumeni syndrome
is rare, with approximately 400 known families.
