607998.0004; CEROID LIPOFUSCINOSIS, NEURONAL 2 |
| Identified Mutation |
IVS5AS, G>C, -1; Sleat et al. [Science 277: 1802-1805, (1997)] described
compound heterozygosity in 2 sibs with LINCL. One allele carried the
arg208-to-ter nonsense mutation (204500.0003); the other allele showed a
splice site mutation, a G-to-C transversion of the consensus AG 3-prime
splice acceptor site immediately preceding 523T of the cDNA sequence. |
| Remarks |
CABM020; clinically affected; CLN2 protease deficient; donor subject is a compound heterozygote: one allele carries a G-to-A transition at nucleotide g.3085 (c.380G>A) which converts the arg-127 codon (CGA) to a Gln codon (CAA), resulting in a missense mutation in exon 4 of the CLN2 (TPP1) gene [ARG127GLN (R127Q)] and a second allele carries a G-to-C transversion in the invariant AG of a 3' splice junction in intron 5 at nucleotide g.3556 (IVS5-1G>C) of the CLN2 (TPP1) gene. |
