Genes affected

CLCA1 (HGNC:2015): (chloride channel accessory 1) This gene encodes a member of the calcium sensitive chloride conductance protein family. To date, all members of this gene family map to the same region on chromosome 1p31-p22 and share a high degree of homology in size, sequence, and predicted structure, but differ significantly in their tissue distributions. The encoded protein is expressed as a precursor protein that is processed into two cell-surface-associated subunits, although the site at which the precursor is cleaved has not been precisely determined. The encoded protein may be involved in mediating calcium-activated chloride conductance in the intestine. [provided by RefSeq, Jul 2008]

The c.432A>T (p.L144F) alteration is located in exon 3 (coding exon 3) of the CLCA1 gene. This alteration results from a A to T substitution at nucleotide position 432, causing the leucine (L) at amino acid position 144 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
