There is good evidence from linkage analysis and mouse model knockouts that the endothelin-1 gene (EDN1) is a good candidate for non-syndromic orofacial cleft (OFC) disease. EDN1 maps to the chromosomal region of the OFC1 locus in 6p23. Therefore we have examined three other candidate genes in the endothelin pathway (ECE1, EDNRA and EDNRB, which map to chromosomes 1, 4 and 13 respectively) in a linkage study of 9 families with OFC, where the disorder is not linked to chromosome 6p23. The total lod score for these 9 multiplex families never exceeded - 2.00 and thus our data suggest that EDN1 and related genes are not involved in non-syndromic familial OFC.

Abstract
There is good evidence from linkage analysis and mouse model knockouts that the endothelin-1 gene (EDN1) is a good candidate for non-syndromic orofacial cleft (OFC) disease. EDN1 maps to the chromosomal region of the OFC1 locus in 6p23. Therefore we have examined three other candidate genes in the endothelin pathway (ECE1, EDNRA and EDNRB, which map to chromosomes 1, 4 and 13 respectively) in a linkage study of 9 families with OFC, where the disorder is not linked to chromosome 6p23. The total lod score for these 9 multiplex families never exceeded - 2.00 and thus our data suggest that EDN1 and related genes are not involved in non-syndromic familial OFC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
