1p36 deletion syndrome is a congenital genetic disorder characterized by moderate to severe intellectual disability, delayed growth, hypotonia, seizures, limited speech ability, malformations, hearing and vision impairment, and distinct facial features. The symptoms may vary, depending on the exact location of the chromosomal deletion. [1]

In this article, we review recent successes in the effort to map and identify the genes and genomic regions that contribute to specific 1p36-related phenotypes. In particular, we highlight evidence implicating MMP23B, GABRD, SKI, PRDM16, KCNAB2, RERE, UBE4B, CASZ1, PDPN, SPEN, ECE1, HSPG2, and LUZP1 in various 1p36 deletion phenotypes.

Chromosome 1p36 deletion syndrome (1p36DS) is one of the most common terminal deletion syndromes (incidence between 1/5000 and 1/10,000 live births in the American population), due to a heterozygous deletion of part of the short arm of chromosome 1.

Chromosome 1p36 deletion syndrome is caused by a deletion of genetic material from a specific region in the short (p) arm of chromosome 1. Most cases are not inherited; only about 20% of the cases of people with 1p36 deletion syndrome inherit the chromosome with a deleted segment from an unaffected parent.

Most genes contributing to the phenotypic features of 1p36 deletion syndrome are located distal to marker D1S2870 (chr1:6,289,764–6,289,973), this region is subsequently referred to as the distal or classical critical region 2.

People with 1p36 deletion syndrome have lost a small but variable amount of genetic material from one of their 46 chromosomes. Chromosomes are made up of DNA and are the structure in the nucleus of the body’s cells that carry genetic information (known as genes), telling the body how to develop and function.

2007年11月15日 · Monosomy 1p36 results from a heterozygous deletion of the most distal chromosomal band on the short arm of chromosome 1. Occurring in approximately 1 in 5,000 live births, monosomy 1p36 is the most common terminal deletion observed in humans.

The constitutional deletion of chromosome 1p36 results in a syndrome with multiple congenital anomalies and mental retardation (Shapira et al., 1997). Monosomy 1p36 is the most common terminal deletion syndrome in humans, occurring in 1 in 5,000 births (Shaffer and Lupski, 2000; Heilstedt et al., 2003).
