Genes affected

SCRN1 (HGNC:22192): (secernin 1) This gene likely encodes a member of the secernin family of proteins. A similar protein in rat functions in regulation of exocytosis in mast cells. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

The c.802A>G (p.S268G) alteration is located in exon 6 (coding exon 6) of the SCRN1 gene. This alteration results from a A to G substitution at nucleotide position 802, causing the serine (S) at amino acid position 268 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
