People here are a collaboration of  knowledge.
Would anybody happen to know what disease is caused by a lack of a second number 5 chromosome?

Generally aneuploidy (wrong number of chromosomes) in any of the larger chromosomes is embryonic lethal - that is embryos with lacking a copy or with an extra copy of one of the chromosomes are generally aborted spontaneously, resulting in a miscarriage.  Aneuploidy will generally only result in a viable fetus if it is in one of the smaller chromosomes (e.g. trisomy 21 - Down Syndrome).  Viable monosomies are even more rare, although some exist (e.g. XO - Turner's syndrome).  To the best of my knowledge, monosomy 5 would be embryonic lethal.  However, there is a condition called cri du chat syndrome in which the affected individual is lacking a portion of one of his/her copies of chromosome 5.

Ok thank you. I was having trouble finding a disease caused by the lack of a second number 5 chromosome which is what showed up in my given karyotype. My teacher told me to look for other disease related to deletions of parts of chromosome 5.
