Genes affected

SCG3 (HGNC:13707): (secretogranin III) The protein encoded by this gene is a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. Granins may serve as precursors for biologically active peptides. Some granins have been shown to function as helper proteins in sorting and proteolytic processing of prohormones; however, the function of this protein is unknown. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

Ambry Genetics

Nov 17, 2022

The c.538C>T (p.L180F) alteration is located in exon 5 (coding exon 5) of the SCG3 gene. This alteration results from a C to T substitution at nucleotide position 538, causing the leucine (L) at amino acid position 180 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
