The research objective was to identify and describe the facial characteristics of heterozygous gene carriers who show minor expression of the disorder.<\/jats:p><jats:p>In this study of 13 HED families with 16 affected males, 12 carriers, and 12 normal individuals, affected individuals had at least 3 of the following 4 clinical signs and symptoms: a) hypodontia, b) hypohidrosis, c) hypotrichosis, and d) clinically distinct facial physiognomy. By contrast, the gene carriers manifested only one or 2 or none of the 4 clinical manifestations.<\/jats:p><jats:p>In a preliminary comparison of gene carriers vs. normal individuals, we have generated 2 discriminant functions (each based on 3 facial measurements taken either from the lateral or frontal cephalograms). These 2 functions correctly diagnose 100% of the gene carriers and normal HED relatives.<\/jats:p><jats:p>Facial anomalies characteristic of the gene carriers were 1) abnormally narrow and short maxillary width and palatal depth dimensions; 2) very small and retrusive malar and maxillary regions; 3) markedly reduced lower facial depth, height and width dimensions; 4) small head height, prominent forehead, and high\u2010set orbits; 5) a generalized, symmetric reduction of the whole craniofacial complex.<\/jats:p>","DOI":"10.1002\/ajmg.1320350120","type":"journal-article","created":{"date-parts":[[2005,6,12]],"date-time":"2005-06-12T03:34:51Z","timestamp":1118547291000},"page":"105-114","source":"Crossref","is-referenced-by-count":33,"title":["Facial
