Genes affected

SCGN (HGNC:16941): (secretagogin, EF-hand calcium binding protein) The encoded protein is a secreted calcium-binding protein which is found in the cytoplasm. It is related to calbindin D-28K and calretinin. This protein is thought to be involved in KCL-stimulated calcium flux and cell proliferation. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 12, 2023

The c.763G>T (p.V255L) alteration is located in exon 11 (coding exon 11) of the SCGN gene. This alteration results from a G to T substitution at nucleotide position 763, causing the valine (V) at amino acid position 255 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
