Association between gynecomastia and aromatase (CYP19) polymorphisms.
OBJECTIVE Aromatase cytochrome P45019 (CYP19) is a key enzyme in estrogen biosynthesis, and polymorphisms within its gene are associated with an increased risk of estrogen-dependent diseases. Enhanced estrogen stimulation of breast tissue in men may lead to gynecomastia. We assessed whether intron 4 (TTTA)n repeat and TCT deletion/insertion polymorphisms and an exon 10 (3'-UTR) C/T single nucle...
متن کاملAssociation between MTNR1A and CYP19 Genes Polymorphisms and Economic Traits in Kurdi Sheep
The ovine melatonin receptor 1A (MTNR1A) and aromatase (CYP19) genes were structurally characterized and the association between their variants and reproductive and growth traits was studied in Kurdi sheep at Kurdi sheep breeding station located in Shirvan, Iran. The genomic DNA was extracted by guanidine thiocyanate-silica gel method. Polymerase chain reaction was carried out to amplify 824 bp...
متن کاملAromatase and gynecomastia.
An imbalance between estrogen action relative to androgen action at the breast tissue level results in gynecomastia. Enhancement of aromatization of androgens to estrogens is important in the pathogenesis of gynecomastia associated with obesity, aging, puberty, liver disease, thyrotoxicosis, 17-oxosteroid reductase deficiency. Klinefelter's syndrome, and neoplasms of the testes, adrenals and li...

متن کاملThe association between genetic polymorphisms in CYP19 and breast cancer risk in Korean women.
Aromatase encoding by the CYP19 gene catalyzes the conversion of androgens to estrogens. In order to determine if polymorphisms of the CYP19 gene are associated with breast cancer risk, we analyzed the frequency of tetranucleotide (TTTA) tandem repeats and a 3-bp insertion (I)/deletion (D) polymorphism in intron 4 of the CYP19 gene in genomic DNA from 70 Korean breast cancer patients and 102 ag...
