We have been seeing Genetics at Children’s in order to find out if what Chloe has is hereditary. The Genetics want to out rule any chromosomal disorders as a cause of her problem. Therefore, Chloe, Dennis, and I have gone through chromosome testing. Chloe has duplication on chromosome 2p22.2. It turns out that Chloe’s daddy has the same duplication. Not sure what this means yet but my husband will be going through some testing to find out if he has any situs inversus. Abdominal Situs inversus may be linked by autosomal recessive, dominant or X-linked. Chloe is also having DNA testing done by the NIH in Maryland.
Recessive, autosomal: A genetic condition that appears only in individuals who have received two copies of an autosomal gene, one copy from each parent.
Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. Therefore, Dominant genes show their effect even if there is only one copy of that gene in the pair.
X-linked diseases are single gene disorders that reflect the presence of defective genes on the X chromosome.

they plan on doing some genetic testing on my daughter, grandaughter and son in law soon, before the next baby is born.
