Langer-Giedion Syndrome |

Langer-Giedion Syndrome (LGS) or type II trichrhinophalangeal syndrome (TRP) is usually sporadic and features may overlap with type I TRP, which is usually autosomal dominant. Theoretically, deletion of long arm of chromosome 8 in the region q24.11-q24.13 seen in approximately 50% of patients can be detected antenatal. But there is no previous attempt at antenatal diagnosis in literature possibly because only a few cases of vertical transmission have been reported so far. In addition to aforementioned features, other symptoms like hearing loss, submucous cleft palate, skin and joint laxity, melanocytic nevi, myopia, growth delay, mental deficiency, epilepsy, psychological disturbances, sarcomatous changes in exostoses, uretrohydronephrosis, hematometra, endocrine problems like diabetes mellitus and hypothyroidism, epiphyseal dysplasia, avascular necrosis of femoral head and decreased reproductive fitness may be associated and require a multidisciplinary therapeutic approach. Bony exostoses require excision only if neurovascular or sarcomatous complications occur. Despite these numerous associated problems, the prognosis for general health is good. Differential diagnoses include Ehlers-Danlos syndrome (because of excessive redundancy and looseness of skin especially at birth and during early infancy) and Osteochondromatosis syndrome or Ollier’s disease (if striking facial features of LGS are absent).
