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]

The c.1936G>T (p.A646S) alteration is located in exon 18 (coding exon 15) of the CRACR2A gene. This alteration results from a G to T substitution at nucleotide position 1936, causing the alanine (A) at amino acid position 646 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
