User :   I am 13 weeks pregnant and my child was found to have a slightly longer than normal Chromosome 4... Can she still be normal?
Doctor :   Hi
Doctor :   Dr here
User :   Hello
Doctor :   yes , that is not a problem
User :   The reason for the test was that her Trans Nuchal test showed fluid at 3.5
User :   2.5 - 3.5 is the acceptable range
Doctor :   usually if there is a absence of a chromosome would be a matter of concern
User :   What about duplication
User :   Trisomy
User :   I have been reaidng
User :   reading
Doctor :   chromosomal anomalies include , defects in number (that is increase or decrease in chromosomes)
User :   What about length or size
Doctor :   monosomy, is decrease in the copy of a chromosome, for example turners syndoirme
User :   Should My Husband and I have our chromosome mapped?
Doctor :   about the length, usually during gene polymorphism , the arms of the chms can be switched
User :   I do have a heart murmur. Could that be linked to Chromosome 4
Doctor :   so size and length are not a factor to be worried about
User :   Interesting
Doctor :   may i know both your age please ?
User :   And the nuchal at 3.5 should be okay as well
User :   37
User :   The test showed all other chromosomes to be normal
Doctor :   may i also know if any echo was done to evaluate the murmur ?
User :   My husband is 37
Doctor :   so both of you are 37 ?
User :   yes
Doctor :   ok
Doctor :   was an echo done ?
User :   The heart sounds normal, but they want to redo it at 16 weeks since 13 weeks is kinda early
Doctor :   ok
Doctor :   as far as the results of the chromosome study are concerned, there is nothing to be worried
User :   Thank you! I have been on edge since I got the news.
Doctor :   you are most welcome
Doctor :   Is there anything else i can help you with ?
User :   No. This is good news. We will keep monitoring as we go. But, you have helped me be more hopeful
Doctor :   you are most welcome
