| 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. |

| Allelic Variant 1 |
Y231Y; CANAVAN DISEASE SILENT POLYMORPHISM |
| Identified Mutation |
TYR231TYR; In Ashkenazi Jewish patients with Canavan disease (271900), Kaul et al. (1994) identified a 693C-A nonsense mutation in exon 5 of the ASPA gene (Y231X). They also identified a silent polymorphism, 693C/T. Expression of the mutation in COS-1 cells showed a complete loss of ASPA enzyme activity. |

| Remarks |
Clinically affected; mild case; skin blotching; increased sweating; absent deep tendon reflexes; no flare response to histamine test; no fungiform papillae on tongue; severe corneal problems and was legally blind until a corneal transplant; vomiting crsis approximately every 6 months; spinal problems with some minor rotation of vertebrae; postural hypotension; normal height; menarchy started at 15 years and was very irregular; mother is GM04634/GM04635; father is GM04632; donor subject is homozygous for 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; donor subject is also heterozygous for a silent polymorphism in the ASPA gene: 693C>T [Tyr231Tyr (Y231Y)] |
