1P36 DELETION SYNDROME, RARE (NIH)

1p36 deletion syndrome, rare (nih) definition: 1p36 deletion syndrome also known as monosomy 1p36 is a disorder of the chromosomes in which chromosome 1 loses the end part of its short arm. This disorder was first depicted during the late 90's & the early parts of 2000's. FISH testing is often required to be able to confirm a diagnosis. This condition can occur as a 'pure' case or it can occur together with other imbalances of the chromosome.
