Summaries for 12q14 Microdeletion Syndrome

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 94063Disease definition12q14 microdeletion syndrome is characterised by mild intellectual deficit, failure to thrive, short stature and osteopoikilosis. It has been described in four unrelated patients. The syndrome appears to be caused by a heterozygousdeletion at chromosome region 12q14, which was detected in three of the four patients. The deleted region contains the LEMD3 gene: mutations in this gene have already been implicated in osteopoikilosis.Visit the Orphanet disease page for more resources.

MalaCards based summary : 12q14 Microdeletion Syndrome, also known as osteopoikilosis-short stature-intellectual disability syndrome, is related to silver-russell syndrome and isolated growth hormone deficiency, type ia. An important gene associated with 12q14 Microdeletion Syndrome is HMGA2 (High Mobility Group AT-Hook 2), and among its related pathways/superpathways is DNA Damage/Telomere Stress Induced Senescence. Affiliated tissues include kidney, skin and bone, and related phenotypes are hypertelorism and frontal bossing
