Genes affected
CAPS (HGNC:1487): (calcyphosine) This gene encodes a calcium-binding protein, which may play a role in the regulation of ion transport. A similar protein was first described as a potentially important regulatory protein in the dog thyroid and was termed as R2D5 antigen in rabbit. Alternative splicing of this gene generates two transcript variants. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.259C>T (p.R87W) alteration is located in exon 3 (coding exon 2) of the CAPS gene. This alteration results from a C to T substitution at nucleotide position 259, causing the arginine (R) at amino acid position 87 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
