What is 18q deletion syndrome and how is it treated?

What is 18q deletion syndrome and how is it treated?

See below: About 1 in every 40, 000 babies is born with distal 18q-.
Treatment is to address the resultant medical problems. No two people with distal 18q- are exactly alike. One person may have different medical and developmental concerns from another person with distal 18q-. Also, remember that no one with distal 18q- will have all of the features.

My daughter has 22q11 deletion. One of the questions on here said that 38 was old for someone with di george. Is there an average life expectancy?

My daughter has 22q11 deletion. One of the questions on here said that 38 was old for someone with di george. Is there an average life expectancy?

Things change.: For genetic syndromes, things are changing rapidly. A child with a chromosomal disorder born 30 years ago would not have the life expectancy of a child born today with the same genetic disorder. There were many reasons children with 22q11.2 syndrome may have died in the past and most of these conditions are managed much better now and into the future. Life expectancy is constantly
improving. ...Read more

Is a deletion necessary a bad problem?

Is a deletion necessary a bad problem?

Depends: The effect of a chromosome deletion varies case by case & outcome varies. If a deleted segment is carried on another chromosome, the body has the information it needs miss filed but available for use & many people with balanced translocations live long prosperous lives without knowing.When the deletion sits alone, minor to major defects & disability are likely if the baby makes it thru pregnancy. ...Read more

My 5yo girl has been diagnosed with 1q21.1 duplication syndrome, 1q21.1 deletion syndrome and 7q11.22 duplication. Please can you tell me more :(?

Genetic disorders: Your daughter's cells lost tiny portions of some genes on her chromosomes and doubled up on other tiny portions. This happened around the time the egg that became her was fertilized. It was no one's fault. The effects vary, but can include a small head, speech and motor skill disabilities, ; learning disabilities, ; behavior problems, as well as seizures, cataracts, ; heart abnormalities. ...Read more

I have a child with a chfromesome deletion 4p15.3 to be exact what does this mean? And.Is. It bad?

Loss of data: Our chromosomes(c)contain the guidelines that permit our body parts to develop and defines how we make the enzymes and proteins necessary for life. The c has a short arm, the p arm and a long arm, the q.A loss of material in the 4p15.3 means the material is gone from that site, so the information it contained is lost.A geneticist can provide you with more specific data. ...Read more

My sibling has VCFS. Is it possible for me to be a "carrier" of microdeletion 22q11 and pass it on to my child if i don't have the deletion/syndrome?

My sibling has VCFS. Is it possible for me to be a "carrier" of microdeletion 22q11  and pass it on to my child if i don't have the deletion/syndrome?

Microdeletion 22q11: Hello Rosette. Inheritance of Microdeletion 22q11 is autosomal dominant & just one copy of the gene causes the actual syndrome. This prevents you being a "carrier" (silently carrying the gene but not the syndrome). Frequently, it is not inherited and a new gene mutation. For some, Microdeletion 22q11 can be subtle & diagnosed in adulthood so I recommend Genetic counseling due to a sib w/VCFS. ...Read more

It would now, from a: Chromosomal Microarray, molecular genetic testing that is standard of practice for geneticists & developmental pediatricians for infants & children with developmental delays &/or Autistic Spectrum Disorder. A standard karyotype would not have identified a small sequence of deleted genes at 22q.11.2., only a FISH test of Chromosome 22 in the VCF region., done if there was clinical suspicion. ...Read more

I am wondering if people living with c-18Q- chromosomal deletion syndrome have trouble fighting off infections or have low levels of iga.

I am wondering if people living with c-18Q-  chromosomal deletion syndrome have trouble fighting off infections or have low levels of iga.

18q- means a piece : of The long arm of the 18th chromosome is missing. There are hundreds of different genes located on the long arm, so there are potentially hundreds of different combinations of genes which might be missing and they all could cause different problems depending on the function of the genes missing.

Our infant who is being checked for 22q deletion had an echo which found papvc, but no asd was seen. He has a low murmur. Could it have been missed?

Our infant who is being checked for 22q deletion had an echo which found papvc, but no asd was seen. He has a low murmur. Could it have been missed?

Possibly: The typical atrial septal defect that is associated with partial anomalous pulmonary venous connection is a sinus venosus asd. It is possible for a sinus venosus ASD to be missed if the sonographer did not record images in that area. On the other hand, it is possible to have papvc without an asd, although that is rare. ...Read more
