Genes affected

CLCA4 (HGNC:2018): (chloride channel accessory 4) The protein encoded by this gene belongs to the calcium sensitive chloride conductance protein family. To date, all members of this gene family map to the same site on chromosome 1p31-p22 and share high degrees of homology in size, sequence and predicted structure, but differ significantly in their tissue distributions. Alternative splicing results in multiple transcript variants, only one of which is thought to be protein coding. [provided by RefSeq, Dec 2008]

The c.964C>T (p.R322C) alteration is located in exon 7 (coding exon 7) of the CLCA4 gene. This alteration results from a C to T substitution at nucleotide position 964, causing the arginine (R) at amino acid position 322 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
