Genes affected

RCAN2 (HGNC:3041): (regulator of calcineurin 2) This gene encodes a member of the regulator of calcineurin (RCAN) protein family. These proteins play a role in many physiological processes by binding to the catalytic domain of calcineurin A, inhibiting calcineurin-mediated nuclear translocation of the transcription factor NFATC1. Expression of this gene in skin fibroblasts is upregulated by thyroid hormone, and the encoded protein may also play a role in endothelial cell function and angiogenesis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2011]

The c.256G>T (p.A86S) alteration is located in exon 2 (coding exon 2) of the RCAN2 gene. This alteration results from a G to T substitution at nucleotide position 256, causing the alanine (A) at amino acid position 86 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
