25866837 identified two novel CTNS splicing deletions in a Chinese IC family, one at the donor site of exon 6 of CTNS and the other at the acceptor site of exon 8
25811383 cystinosin-deficient cells had abnormal shape and distribution of the endo-lysosomal compartments and impaired endocytosis, with decreased surface expression of multiligand receptors and delayed lysosomal cargo processing.
25326109 We recommend that black South African and Cape Coloured patients presenting with cystinosis be tested for CTNS-c.971-12G > A in the first instance, with the possibility of prenatal testing being offered to at-risk families.
23640116 The present data exhibit a fundament for molecular carrier detection and prenatal diagnosis of a relatively large percentage of Iranian patients suffering from NC
22649030 results objectify the pigmentation defect in patients with cystinosis. We also identify the role of CTNS in melanogenesis and add a new gene to the list of the genes involved in the control of skin and hair pigmentation
22544350 CTNS-LKG represents 5-20 % of CTNS transcripts, with the exception of the testis that expresses both isoforms in equal proportions.
22450360 Mutation analysis of CTNS in six cystinosis patients from four families in Thailand. Using PCR sequencing of the entire coding regions, study identified all eight mutant alleles, including two mutations, p.G309D and p.Q284X, that have not been previously reported.
22363504 Cystinosin, MPDU1, SWEETs and KDELR belong to a well-defined protein family with putative function of cargo receptors.[cytonosin]
22232659 cystinosin exports the proteolysis-derived dimeric amino acid cystine from lysosomes and is impaired in cystinosis.
21786142 Report CTNS mutations in Turkish cystinosis patients.
