Genes affected
RCN1 (HGNC:9934): (reticulocalbin 1) Reticulocalbin 1 is a calcium-binding protein located in the lumen of the ER. The protein contains six conserved regions with similarity to a high affinity Ca(+2)-binding motif, the EF-hand. High conservation of amino acid residues outside of these motifs, in comparison to mouse reticulocalbin, is consistent with a possible biochemical function besides that of calcium binding. In human endothelial and prostate cancer cell lines this protein localizes to the plasma membrane.[provided by RefSeq, Jan 2009]

The c.302C>G (p.T101S) alteration is located in exon 2 (coding exon 2) of the RCN1 gene. This alteration results from a C to G substitution at nucleotide position 302, causing the threonine (T) at amino acid position 101 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
