<div class="portlet_content ln">Facial dysmorphism, hypertrichosis, epilepsy, intellectual/developmental delay, and gingival overgrowth syndrome (FHEIG) is a neurodevelopmental disorder characterized by these cardinal features. The distinctive facial gestalt includes bushy eyebrows, long eyelashes, short philtrum, thin and everted upper lip, and prominent upper and lower vermilion. Hypertrichosis is significant and generalized, and gingival overgrowth varies in severity. Developmental delay is variable, and seizures or EEG anomalies are present (Bauer et al., 2018). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>

<div class="spaceAbove">Congenital dysplasia of the hip (CDH) is an abnormality of the seating of the femoral head in the acetabulum. Its severity ranges from mild instability of the femoral head with slight capsular laxity, through moderate lateral displacement of the femoral head, without loss of contact of the head with the acetabulum, up to complete dislocation of the femoral head from the acetabulum. It is one of the most common skeletal congenital anomalies (summary by Sollazzo et al., 2000).&#13; Acetabular dysplasia is an idiopathic, localized developmental dysplasia of the hip that is characterized by a shallow hip socket and decreased coverage of the femoral head. Its radiologic criteria include the center-edge angle of Wiberg, the Sharp angle, and the acetabular roof obliquity. Most patients with acetabular dysplasia develop osteoarthritis (165720) after midlife, and even mild acetabular dysplasia can cause hip osteoarthritis (summary by Mabuchi et al., 2006).&#13; CDH occurs as an isolated anomaly or with more general disorders represented by several syndromes and with chromosomal abnormalities such as trisomy 18 (Wynne-Davies, 1970).&#13; Genetic Heterogeneity of Developmental Dysplasia of the Hip&#13; Developmental dysplasia of the hip-1 (DDH1) maps to chromosome 13q22; DDH2 (615612) maps to chromosome 3p21.&#13; DDH3 (620690) is caused by mutation in the LRP1 gene (107770) on chromosome 12q13.</div>
