Summaries for Potocki-Shaffer Syndrome

NIH Rare Diseases : 52 Potocki-Shaffer syndrome is a contiguous gene deletion syndrome associated with deletions in a specific region of chromosome 11 (11p11.2). The characteristic features of Potocki-Shaffer syndrome include openings in the two bones that form the top and sides of the skull (enlarged parietal foramina), multiple benign (non-cancerous) bone tumors called exostoses, intellectual disability , developmental delay , a distinctive facial appearance, autism spectrum disorder , and problems with vision and hearing. In some cases, individuals with the syndrome may have a defect in the heart, kidneys, or urinary tract. Multiple other features or health problems have been reported in individual cases. The features of Potocki-Shaffer syndrome result from the loss of several genes on the short (p) arm of chromosome 11 . In particular, the deletion of a gene called ALX4 causes enlarged parietal foramina (openings in the two bones that form the top and sides of the skull), while the loss of another gene, EXT2 , causes the multiple exostoses (benign bone tumors) . Another condition called WAGR syndrome is caused by a deletion of genetic material in the p arm of chromosome 11, specifically at position 11p13. Occasionally, a deletion is large enough to include the 11p11.2 and 11p13 regions. Individuals with such a deletion have signs and symptoms of both Potocki-Shaffer syndrome and WAGR syndrome . [ A referral to an early childhood intervention and developmental-behavioral specialist and evaluation for vision and hearing problems at the time of diagnosis is recommended. A full skeletal survey at the time of diagnosis or by age 3 years, whichever is later, should also be completed.

MalaCards based summary : Potocki-Shaffer Syndrome, also known as chromosome 11p11.2 deletion syndrome, is related to parietal foramina and peeling skin syndrome 1. An important gene associated with Potocki-Shaffer Syndrome is PSS (Potocki-Shaffer Syndrome). Affiliated tissues include heart, kidney and bone, and related phenotypes are global developmental delay and micrognathia

Genetics Home Reference : 25 Potocki-Shaffer syndrome is a disorder that affects development of the bones, nerve cells in the brain, and other tissues. Most people with this condition have multiple noncancerous (benign) bone tumors called osteochondromas. In rare instances, these tumors become cancerous. People with Potocki-Shaffer syndrome also have enlarged openings in the two bones that make up much of the top and sides of the skull (enlarged parietal foramina). These abnormal openings form extra "soft spots" on the head, in addition to the two that newborns normally have. Unlike the usual newborn soft spots, the enlarged parietal foramina remain open throughout life. The signs and symptoms of Potocki-Shaffer syndrome vary widely. In addition to multiple osteochondromas and enlarged parietal foramina, affected individuals often have intellectual disability and delayed development of speech, motor skills (such as sitting and walking), and social skills. Many people with this condition have distinctive facial features, which can include a wide, short skull (brachycephaly); a prominent forehead; a narrow bridge of the nose; a shortened distance between the nose and upper lip (a short philtrum); and a downturned mouth. Less commonly, Potocki-Shaffer syndrome causes vision problems, additional skeletal abnormalities, and defects in the heart, kidneys, and urinary tract.

OMIM : 56 Potocki-Shaffer syndrome is a rare contiguous gene deletion syndrome due to haploinsufficiency of the 11p12-p11.2 region and is characterized by craniofacial abnormalities, developmental delay, intellectual disability, multiple exostoses (168500), and biparietal foramina (605957) (summary by Swarr et al., 2010).

UniProtKB/Swiss-Prot : 73 Potocki-Shaffer syndrome: A syndrome characterized by foramina parietalia permagna, multiple exostoses, and craniofacial dysostosis and mental retardation in some cases.
