ATM exon 24 allele counts from 66 independent breast cancer cases and 126 unrelated controls.

The table summarizes data from Larson et al. [13]. The seven cases with sequencing shared an intronic marker at ATM as well as a rare HRAS allele with their affected sibling. Omitting the first occurrence of the variant among sequenced cases (in parentheses) permits comparing a pooled detection rate of 8/65 in cases to 4/126 in controls ( by Fisher's exact test, one-sided).
