Androgen receptor gene mutation in male breast cancer.
Abstract
We screened thirteen male breast cancers for the presence of germline mutations in exons 2 and 3 encoding the DNA-binding domain of the androgen receptor. These two exons were amplified from genomic DNA extracted from patients' white blood cells. In one of these thirteen patients, single strand conformation polymorphism and direct sequencing detected a guanine-adenine point mutation at nucleotide 2185 that changes Arg608 into Lys in a highly conserved region of the second zinc finger of the androgen receptor. This mutation occurred in a 38 year old man with partial androgen insensitivity syndrome and normal androgen-binding capacity in cultured genital skin fibroblasts. To our knowledge, only one germline Arg to Gln androgen receptor gene mutation has been previously reported at position 607 in male breast cancer. This androgen receptor mutation along with the Arg608 into Lys mutation we describe, suggests that this genetic abnormality is not fortuitous: a decrease in androgen action within the breast cells could account for the development of male breast cancer by the loss of a protective effect of androgens on these cells. Activation of estrogen regulated genes by the change of DNA-binding characteristics of the mutant androgen receptor cannot, however, be ruled out.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
