Women who are A–T carriers (who have one mutated copy of the ATM gene) have approximately a two-fold increased risk for the development of breast cancer compared to the general population. [19] [20] This includes all mothers of A–T children and some female relatives. The current consensus is that special screening tests are not helpful, but ...
According to COSMIC, the Catalogue Of Somatic Mutations In Cancer, the frequencies with which heterozygous mutations in ATM are found in common cancers include 0.7% in 713 ovarian cancers, 0.9% in central nervous system cancers, 1.9% in 1,120 breast cancers, 2.1% in 847 kidney cancers, 4.6% in colon cancers, 7.2% among 1,040 lung cancers and 11 ...
Mammography is a common screening method, since it is relatively fast and widely available in developed countries. Mammography is a type of radiography used on the breasts. . It is typically used for two purposes: to aid in the diagnosis of a woman who is experiencing symptoms or has been called back for follow-up views (called diagnostic mammography), and for medical screening of apparently ...

The estimated fraction of breast cancer attributed to this variant is reported to be around 1.2% in the US. [ 8 ] Two more CHEK2 gene mutations, CHEK2*S428F, an amino-acid substitution to the kinase domain in exon 11 and CHEK2*P85L, an amino-acid substitution in the N-terminal region (exon 1) have been found in the Ashkenazi Jewish population ...
ATM: Mutations cause ataxia telangectasia; female carriers have approximately double the normal risk of developing breast cancer. [5] PALB2: Studies vary in their estimate of the risk from mutations in this gene and the frequency of mutations in this gene may be different among different populations. [8] It may be moderate risk, or as high as ...
