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.1242C>G (p.D414E) alteration is located in exon 8 (coding exon 8) of the SCRN1 gene. This alteration results from a C to G substitution at nucleotide position 1242, causing the aspartic acid (D) at amino acid position 414 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
