One of the reasons for this intensive clustering phenomenon may be the higher sensitivity of the AFLP technique because the degraded recombination rate near centromere
or telomere, non - equal of restriction enzyme sites and high repeat factor could cause these intensive clustering markers (Strommer et al.
They result from two terminal breaks on both chromosome arms followed by fusion of the broken ends containing the centromere
to form a circular structure leading to the loss of genetic material.
Increased CEP17 copy number may occur because of a focal gain in the centromeric region, polysomy (a duplication of the entire chromosome), a gain of a large portion of chromosome 17, or coamplification of the centromere

We recently identified the triggering event in centriole biogenesis and how its regulation is akin to cell cycle control of DNA replication and centromere
Prior to anaphase, the CPC is highly enriched at the inner centromere
, and ABK activity contributes to spindle and kinetochore assembly, spindle assembly checkpoint signaling, and error correction (Tanaka et al.
Laboratory studies showed a positive ANA >1:2,560 with a centromere
pattern, negative Scl-70, and positive antimitochondrial antibody at 158.
Further subdivision of translocation types can be made according to the exchange of chromosomal material and are classified as: (i) reciprocal, when segments from two different chromosomes have been exchanged; or (ii) robertsonian, in five acrocentric chromosomes (13, 14, 15, 21 and 22), where long arms fuse to form a single chromosome with a single centromere
The chromosomes were classified as metacentric, submetacentric, acrocentric or telocentric based on the ratio between the arms (r) and centromere
index (ic), which was proposed by Guerra (1986).
This includes pervasive transcription of the genome, conservation of many nonprotein-coding sequences, sequence-dependent functions of RNAs transcribed from introns, pseudogenes, repetitive DNA, functions almost independent of the exact nucleotide sequence, chromatin topology in gene expression and centromere
placement, and the light-focusing property of heterochromatin in inverted nuclei.

Secondly complete antibody screening of these patients could not be done even though it is known that a few clinical features of scleroderma are influenced by presence or absence of anti centromere
and anti-Scl 70 antibody.
