| GENE MAPPING & DOSAGE STUDIES - Y CHROMOSOME |
PCR analysis of DNA from this cell culture gave a negative result with a primer for Yq11, DYS227. |

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. |
