Chromosome 9 is one of the 23 pairs of chromosomes in humans.Humans normally have two copies of this chromosome, as they normally do with all chromosomes. It is generally recognised that half of all pregnancies are miscarried, in many cases before a woman even knows she is pregnant. Previous article in issue; Next article in issue; Key Words. Case report. Chromosome 9 is made up of about 141 million DNA building blocks (base pairs) and represents approximately 4.5 percent of the total DNA in cells. Genetic testing is carried out to help parents plan for future pregnancies, rather than as part of the decision making process for the current pregnancy. Identifying genes on each chromosome is an active area of genetic research. Setting. This most often occurs when two sperm fertilize an egg, resulting in an extra copy of the father's genetic material. It is likely that many of these pregnancies are miscarried due to irregularities with genetic material. Found out that I have Chromosome 9 inversion. recurrent pregnancy loss. FISH. Recurrent pregnancy loss (RPL) is a health problem involving about 3% of couples. It contains only 10 exons and 9 introns, 36–38 and encodes two different-sized transcripts (2.8 kb and 4.6 kb) owing to alternative polyadenylation in the 3′ untranslated region. Design.

In a partial or incomplete molar pregnancy, the mother's chromosomes remain but the father provides two sets of chromosomes. The human PGH synthase-2 gene is located on chromosome 1 35 and differs from PGH synthase-1 in that it is much smaller (∼8 kb). "Pregnancy is a long, 10-month journey," said Dr. Draion Burch, an obstetrician and gynecologist at Magee-Womens Hospital at the University of Pittsburgh Medical Center. Patient(s) A 31-year-old woman who had four recurrent early spontaneous abortions.
Trisomy in Pregnancy . However, there are few reports concerning the outcomes of pregnancy in patients with RPL when the patient or their partner has inv(9). Both parents will need to have their chromosomes analysed if their baby is affected by Patau's syndrome caused by a chromosomal translocation. The presence of extra genetic material can cause difficulties for a growing embryo. RPL.

Trisomy 9 is a rare and often fatal chromosomal abnormality that occurs in approximately 2.4 percent of pregnancy losses that occur before the 20th week of pregnancy (spontaneous abortions). Inversion of chromosome 9 (inv[9]) is considered to be a normal variant, and the inv(9) in patients or husbands with recurrent pregnancy loss (RPL) is believed to be harmless. The severity of this disorder depends on the percentage of affected cells.

Chromose 9 Trisomy Complete is a rare triplication of chromosome 9 is in every cell of the body. Remaining cases showed variations in the satellite regions of acrocentric chromosomes and in the pericentric heterochromatic region of chromosome 9 [Table 5].
