Genes affected

AMY1A (HGNC:474): (amylase alpha 1A) Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and glycogen. The human genome has a cluster of several amylase genes that are expressed at high levels in either salivary gland or pancreas. This gene encodes an amylase isoenzyme produced by the salivary gland. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

The c.1036C>T (p.H346Y) alteration is located in exon 8 (coding exon 7) of the AMY1A gene. This alteration results from a C to T substitution at nucleotide position 1036, causing the histidine (H) at amino acid position 346 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
