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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 11, 2024The c.497A>G (p.D166G) alteration is located in exon 7 (coding exon 7) of the SCGN gene. This alteration results from a A to G substitution at nucleotide position 497, causing the aspartic acid (D) at amino acid position 166 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
