| Gene |
IKBKAP |
| Chromosomal Location |
9q31 |
| Allelic Variant 1 |
603722.0001; FAMILIAL DYSAUTONOMIA |
| Identified Mutation |
c.2204+6T>C (IVS20+6T>C); Slaugenhaupt et al. (2001) found that more than 99.5% of disease alleles causing familial dysautonomia (223900) in Ashkenazi Jewish individuals carried a donor splice site mutation (IVS20+6T-C) which leads to deletion of exon 20 from mRNA. Haplotype analyses were consistent with a common founder. Anderson et al. (2001) identified the same mutation in Ashkenazi Jewish patients with familial dysautonomia. |
| Remarks |
Clinically unaffected; donor subject has one allele which has the 2507+6T>C mutation in the IKBKAP gene; this donor splice site mutation (IVS20+6T>C) leads to deletion of exon 20 from the mRNA; the second allele tested negative for the IVS20+6T>C and R696P mutations; affected children are GM05105, GM05106; son of GM09662. |
