Abstract
Uterine Leiomyomata (UL), also called as fibroids are
non- malignant smooth muscle tumors of the uterine myometrium. They may be
solitary or multiple, syndromic or non-syndromic forms, in women of
reproductive age in the third to fifth decade of their life. They may be asymptomatic or larger fibroids are
associated with hemorrhage, pelvic pain, pressure, either increase urinary
frequency or its retention, dysmenorrhoea, dyspareunia, pregnancy related
problems, interference in the development of fetus, repetitive abortions,
premature labor and infertility. The ovarian hormone estrogen is the main
stimulator for the fibroid growth, regress or calcify
after menopause. UL
rarely progresses to malignancy. Global
prevalence is as low as 5-10% in European countries to as high as 60-70 % in
African countries. Around 40 -50 % of fibroids have chromosomal cytogenetic
abnormalities. Believed to arise from a common progenitor cell. Distinct
genetic alterations in fibroids were identified in Exon-2 of Mediator Complex
Subunit 12 (MED-12) gene. In this study twenty-two multiple fibroids were
examined both from the same uterus and from different uteri, of four women, for
somatic mutations in hotspot region of MED-12 gene. Several variants in Exon-2
and flanking intronic regions were seen in the results which provided evidence
that multiple UL in the same uterus may not be clonal in origin. This is the
first study reporting MED-12 sequence variants in UL from South Indian women
and also from multiple fibroids from the same individual.
