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.711G>C (p.E237D) alteration is located in exon 5 (coding exon 5) of the SCRN1 gene. This alteration results from a G to C substitution at nucleotide position 711, causing the glutamic acid (E) at amino acid position 237 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
