Genes affected

CLIC1 (HGNC:2062): (chloride intracellular channel 1) Chloride channels are a diverse group of proteins that regulate fundamental cellular processes including stabilization of cell membrane potential, transepithelial transport, maintenance of intracellular pH, and regulation of cell volume. Chloride intracellular channel 1 is a member of the p64 family; the protein localizes principally to the cell nucleus and exhibits both nuclear and plasma membrane chloride ion channel activity.

Dec 26, 2023

The c.239T>C (p.I80T) alteration is located in exon 3 (coding exon 3) of the CLIC1 gene. This alteration results from a T to C substitution at nucleotide position 239, causing the isoleucine (I) at amino acid position 80 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
