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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2021The c.43G>T (p.A15S) alteration is located in exon 1 (coding exon 1) of the LACRT gene. This alteration results from a G to T substitution at nucleotide position 43, causing the alanine (A) at amino acid position 15 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
