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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.502C>T (p.R168W) alteration is located in exon 7 (coding exon 7) of the SCGN gene. This alteration results from a C to T substitution at nucleotide position 502, causing the arginine (R) at amino acid position 168 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
