m not sure about that but basically most couple compromise their sex- life because of too much pressure. Langer-Giedion Syndrome can be a true contiguous gene deletion syndrome a result of deletions in the the TRPS and EXT1 genes. The lack of a functional EXT1 gene causes the bone exostoses, bone anomalies and facial abnormalities which can be affecting patients. The EXT1 gene as well as the TRPS1 gene are both absent in patients and research suggests that other genes based in the 8q24.11-8q24.13 region of chromosome 8 might be deleted or non-functional also. Longer deletions in this region are seen as mental retardation as well as the other variations in symptoms stated earlier. Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash. Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.
