Summaries for Potocki-Shaffer Syndrome

About this section
NIH Rare Diseases:45 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 bone tumors called exostoses, intellectual disability, developmental delay, a distinctive facial appearance, autism and problems with vision and hearing. in some cases, individuals with the syndrome may have a defect in the heart, kidneys, or urinary tract. 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, while the loss of another gene, ext2, causes the multiple exostoses. 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 at the time of diagnosis and to have an evaluation for vision and hearing problems, as well as a full skeletal survey at the time of diagnosis or by age 3 years, whichever is later, is recommended. last updated: 9/22/2015

MalaCards based summary: Potocki-Shaffer Syndrome, also known as chromosome 11p11.2 deletion syndrome, is related to intellectual disability and parietal foramina 2, and has symptoms including decreased skull ossification, cognitive impairment and exostoses. An important gene associated with Potocki-Shaffer Syndrome is PSS (Potocki-Shaffer Syndrome). Affiliated tissues include bone, kidney and brain.

Genetics Home Reference:23 Potocki-Shaffer syndrome is a disorder that affects development of the bones, brain, and other organs. Most people with this condition have multiple non-cancerous (benign) bone tumors called exostoses. 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.
