Genes affected

CLIC6 (HGNC:2065): (chloride intracellular channel 6) This gene encodes a member of the chloride intracellular channel family of proteins. The gene is part of a large triplicated region found on chromosomes 1, 6, and 21. Alternative splicing results in multiple transcript variants encoding different isoforms.

Nov 17, 2023

The c.248C>T (p.T83I) alteration is located in exon 1 (coding exon 1) of the CLIC6 gene. This alteration results from a C to T substitution at nucleotide position 248, causing the threonine (T) at amino acid position 83 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
