Genes affected

LACRT (HGNC:16430): (lacritin) The protein encoded by this gene is highly expressed in the lacrimal glands and localized primarily to secretory granules and secretory fluid. It augments lacrimal acinar cell secretion, promotes ductal cell proliferation, and stimulates signaling through tyrosine phosphorylation and release of calcium. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 13, 2023

The c.265G>A (p.E89K) alteration is located in exon 4 (coding exon 4) of the LACRT gene. This alteration results from a G to A substitution at nucleotide position 265, causing the glutamic acid (E) at amino acid position 89 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
