Structural chromosome abnormalities occur when there is a change in the structure or parts of a chromosome. The total number of chromosomes is typically 46 total per cell. Structural chromosome abnormalities occur when part of a chromosome is missing, a part of a chromosome is extra, or a part has switched places with another part. Ultimately, this leads to having too much or too little genetic material. This is a cause of some birth defects.Authoritative: Chromosome 5p deletion

Chromosome Deletion?! Huh?? chromosome 5p deletion
A targeted mutation at this locus revealed that it plays an important role in the regulation of embryonic growth and adult behavior. The Mest locus is located in a conserved imprinted domain on mouse chromosome 6 where it is thought to play a key role in the regulation of neighboring maternally expressed genes Copg2 and Klf14 since it contains the only potential imprinting center IC identified thus far in this domain, a differentially chrlmosome region DMR methylated in oogenesis. Here we describe new larger isoforms of the Mest mRNA, referred to as MestXL, that are generated via alternative polyadenylation and transcribed chromosome 5p deletion than 10kb into the adjacent antisense gene Copg2 exclusively in the developing central nervous system.
The MestXL isoforms appear to regulate the allelic usage at Copg2, but not at Klf14, in embryonic neural tissues, as Copg2 is preferentially maternally expressed only in these tissues presumably due to transcriptional interference from MestXL on the paternal chromosome. Our results therefore establish the Mest DMR as an IC and propose a new mechanism to regulate allelic usage chromosome 5p deletion imprinting at sense-antisense gene pairs in mammalian genomes, via tissue-specific alternative polyadenylation and transcriptional interference.
Here we show that chromosome 5p deletion of miR is imprinted and that its levels are reduced from the mutant MestKO chromosomr. Additionally, we identify several candidate target genes of miR by RNA-seq analysis on primary mouse fibroblasts that under-express miR Our investigation of MestXL and miR, two unique alternative functions of the Mest locus, demonstrates that the Mest locus is involved in two types of RNA-mediated regulation and ultimately contributes to the understanding of genomic imprinting and microRNAs in mammalian biology.]
