Summaries for Mucoepithelial Dysplasia, Hereditary

GARD : 20 Hereditary mucoepithelial dysplasia (HMD) is a very rare condition that affects the skin, hair, mucosa (areas of the body that are lined with mucus), gums (gingiva), eyes, nose and lungs. Symptoms begin in infancy and vary in severity from person to person. The most common symptoms of this condition include hair loss ( alopecia ), patchy red skin around the perineum (the area between the anus and external genitalia); and red gums. Small, skin-colored bumps ( keratosis pilaris ) and early development of cloudy lens ( cataracts ) are also common. Other symptoms may include eye disease that gets worse over time, lung disease and a rough, red tongue. Intelligence is normal. The exact cause of HMD is still unknown, but it is thought to be an abnormality in desmosomes and gap junctions, which are cell structures involved in cell-to-cell contact. HMD appears to be inherited in an autosomal dominant pattern, but has occurred in individuals with no family history of the condition. The diagnosis of HMD is based on the symptoms and other skin and eye disorders need to be excluded. HMD is very rare and has been reported in less than 30 people in the literature. Treatment typically focuses on individual symptoms of the condition. The long-term outlook for people with HMD is unknown.

MalaCards based summary : Mucoepithelial Dysplasia, Hereditary, also known as hereditary mucoepithelial dysplasia, is related to ichthyosis follicularis atrichia photophobia syndrome and newborn respiratory distress syndrome. An important gene associated with Mucoepithelial Dysplasia, Hereditary is SREBF1 (Sterol Regulatory Element Binding Transcription Factor 1). Affiliated tissues include skin, eye and tongue, and related phenotypes are cataract and gingival overgrowth

OMIM® : 57 Hereditary mucoepithelial dysplasia (HMD) is a rare autosomal dominant genodermatosis characterized by onset in infancy of a panepithelial defect involving the oral, nasal, conjunctival, vaginal, cervical, perineal, urethral, and bladder mucosa. Patients develop cataracts, blindness, nonscarring alopecia, perineal psoriasiform lesions, and follicular keratoses (Witkop et al., 1982). Although 1 family was reported to have progressive severe interstitial lung disease (Witkop et al., 1979), this feature has not been reported in other families and is not considered a criterion for diagnosis. However, the clinical triad of nonscarring alopecia, well-demarcated fiery red mucosa, and psoriasiform perineal involvement has been consistently observed (review by Boralevi et al., 2005).
