I will try to explain how my chromosomes are abnormal and where I inherited them from.

Cytogenetic analysis of PHA stimulated cultures revealed the karyotype of a FEMALE individual with an apparently balanced translocation between the short arm of one of the chromosome #3 and the long arm of one of the chromosome #6. Breakage and reunion have occured at bands 3p25 and 6q23, and the segments to these breakpoints have been reciprocally exchanged. The rest of the karyotype appears to be normal. Since this patient is a balanced translocation carrier, she has the potential of producing unbalanced gamates, that may be partially monosonic or partially trisomic. (Theoretically, 4/6 of the gametes will be unbalanced (abnormal), 1/6 will carry the balanced translocation like the patient (Tania), and 1/6 will be normal). If the unbalanced gametes are involved in fertilization, the zygote (fetus) may be spontaneously aborted. All future pregnancy of this patient should be monitored via pre-natal chromosome analysis. Genetic counseling is strongly recommended.
There are 23 pairs of Chromosomes in all of us. If you're a male, you will have "y" on the last pair. If you look at the above photo of my Chromosomes, you will notice that the right half of Chromosome #6 is cut off. Now, look at the left half of Chromosome #3 and you will find the missing piece is hooked onto it. It's like a jigsaw puzzle, the pieces are all there but 2 pieces are put in the wrong place. That is what is called "Balanced Translocation". All the members of my family on my dad's (Gaston G. Lachance) side that are carriers like me, have the same #3 and # 6 pairs abnormalities. Now if I would have inherited both my mom's (Nicole L. Leblanc) #3 & #6, I would NOT be a carrier. If I had inherited one of the #3 or #6 from my mom and the other from my dad, I would not have been able to live a normal life, because a piece of the puzzle would have been missing. I either would have been miscarried like my brother (Joel D. Lachance), or been born so abnormal that I would have lived only from a few days to a few months because of too many abnormalities. When I was born, my Mom or Dad didn't know about the abnormal chromosomes. My Grandmother (Elizabeth Coté) One of my cousin (Aunt Jeannette's Daughter) Céline had 3 children. First one was normal but he was a carrier. Second one was so deformed, he only lived a day. Her third one, she tried to keep it by giving permission to the hospital to experiment on trying to repair his deformalities and she said she regretted it, because he died anyway after 45 days of suffering. So out of 3 children, one lived and carried the abnormal genes and 2 didn't make it. My half-sister (Lyna Lachance) gave birth to one when she was only 16 and it was so bad, she decided never to have another child again. My dad's older brother's wife had 4 miscarriages, 2 children a girl & a boy and both are carriers. I have a normal son born in 1991 and he's not a carrier. I had a Baby Boy in November, 2002 and I had him tested by an In 2004, I miscarried one that didn't even make it to the fetus stage. Just a few days ago, in 2005, I had to terminate my pregnancy because he was unbalanced. He had too many deformities that made it so he would have either lived for a short time suffering or he would have died before or during birth. All I know about him is that he had eyes too close together, ears too low and heart defects.
Metaphases examinees: 46/11. Caryotypes: 2. Technique: Bandes "R". Opinion: Un chromosome 3 a acquis par translocation sur ses bras courts un segment des bras long d'un chromosome 6. Formule chromosomique: 46,XX t (3;6) (p26; q23) Date du rapport: 29/09/1977.
Freddy Lachance et Élisabeth Coté se sont marié le 14 Mai, 1923. Ils ont donné naissance à 16 enfants et quatre sont né avant terme. Neuf ont survécu et sept sont decédé du a des chromosomes défectueux. Gilbert et sa fille Johanne ont hérité de cela, Jeannette et ses filles Danielle et Céline Denis, Gaston et ses filles Lyna et Tania ont aussi hérité des chromosomes défectueuses. Les médecins on fait des recherches et ont decouvert que c'était une heridité du coté d'Élisabeth Coté et probablement de la mère a Élisabeth, Geneviève Dufour car elle a eu douze enfants et six n'avait pas de palais ou de luettes. Les tests de Freddy Lachance ont révélé qu'il n'avait pas les chromosomes défectueuses. Les enfants de Freddy Lachance & Élisabeth Coté qui sont décédé du aux chromosomes défectueux: #2. Adrien Lachance, décédé à l'âge de 7 semaines (pas de palais et pas de luette et probablement défaux du coeur). #3. Marie Lucienne Lachance, décédée à l'âge de 3 mois, 18 jours (pas de palais, pas de luette et probablement défaux du coeur). #5. Marie Annette Lachance, décédée à l'âge de 5 mois (pas de palais, pas de luette et probablement défaux du coeur). #10. Jean Louis Lachance, décédé à la naissance (prémature). #12. Marguerite Lachance, décédée à l'âge de 5 mois et 6 jours. (pas de palais, pas de luette et probablement défaux du coeur). #15. Madeleine Lachance, décédée à l'âge de 15 jours. #16. Joseph Pierre Lachance, décédé à l'âge de 1 mois et 6 jours (pas de palais, pas de luette, mains et pieds infirmes et probablement défaux du coeur).
