| Identified Mutation |
5-BP DEL, NT545; Shotelersuk et al. (1998) identified a 5-bp deletion starting at nucleotide 545 resulting in an I69R amino acid substitution and a stop codon at position 73 of the CTNS gene in a patient with classic cystinosis (219800). |
| Remarks |
Clinically affected; diagnosis at age 6; mild disease; mild photophobia; case #1 in Anikster et al Ped Res 47:17-23, 2000; donor subject is a compound heterozygote: allele one has a C>G transversion at the -3 position of the acceptor splice site of IVS10 (IVS10-3C>G) (IVS11-3C>G in RefSeq NM_004937) which results in an insertion of 182 bp between exons 10 and 11 of the CTNS gene and predicts a protein with 28 incorrect amino acids inserted terminating at residue 313; allele two has a 5 bp deletion at nucleotide 545 (545delTCCTT) in exon 5 (exon 6 in RefSeq NM_004937) resulting in a frameshift at codon 69 and a stop at codon 73 [Ile69ter (I69Xfs73)] |
