What is the chromosome 17 mutation?

17q12 deletion syndrome is a condition that results from the deletion of a small piece of chromosome 17 in each cell. The deletion occurs on the long (q) arm of the chromosome at a position designated q12. The signs and symptoms of 17q12 deletion syndrome vary widely, even among affected members of the same family.

What does the 17th chromosome do?

The RARA gene on chromosome 17 provides instructions for making a transcription factor called the retinoic acid receptor alpha (RARα). A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity (transcription) of particular genes.

What is 9q deletion?

Summary. Listen. Chromosome 9q deletion is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material on the long arm (q) of chromosome 9. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved.

What chromosome is linked to autism?

Duplication of a region on the X chromosome leads to a genetic disorder characterized by severe autism, according to a study published 25 November in Annals of Neurology1.

What is the deadliest trisomy?

For example, trisomy 21, or Down syndrome, occurs when a baby has three #21 chromosomes. Other examples are trisomy 18 and trisomy 13, fatal genetic birth disorders. Trisomy 18 occurs in about one out of every 6,000 to 8,000 live births and trisomy 13 occurs in about one out of every 8,000 to 12,000 live births.

What kind of syndrome is 9q34 deletion syndrome?

9q34 deletion syndrome. 9q34 deletion syndrome, is a rare genetic disorder. Terminal deletions of chromosome 9q34 have been associated with childhood hypotonia, a distinctive facial appearance and developmental disability.

Where does the 9q22.3 microdeletion take place?

9q22.3 microdeletion is a chromosomal change in which a small piece of chromosome 9 is deleted in each cell. The deletion occurs on the long (q) arm of the chromosome in a region designated q22.3.

How is 17q12 deletion syndrome inherited from a parent?

[1] [2] 17q12 deletion syndrome is inherited in an autosomal dominant manner; however, in most people with this syndrome, the deletion is not inherited from a parent and occurs sporadically. Less commonly, a person with 17q12 deletion syndrome inherits the deletion from a parent.
