Genes affected

CRACR2A (HGNC:28657): (calcium release activated channel regulator 2A) Enables GTPase activity and calcium ion binding activity. Involved in several processes, including activation of store-operated calcium channel activity; positive regulation of JNK cascade; and store-operated calcium entry. Located in several cellular components, including Golgi apparatus; Weibel-Palade body; and immunological synapse. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Sep 30, 2021

The c.2008C>T (p.R670W) alteration is located in exon 18 (coding exon 15) of the CRACR2A gene. This alteration results from a C to T substitution at nucleotide position 2008, causing the arginine (R) at amino acid position 670 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
