Genes affected
IGSF3 (HGNC:5950): (immunoglobulin superfamily member 3) The protein encoded by this gene is an immunoglobulin-like membrane protein containing several V-type Ig-like domains. A mutation in this gene has been associated with bilateral nasolacrimal duct obstruction (LCDD). [provided by RefSeq, Jun 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.3019G>T (p.A1007S) alteration is located in exon 11 (coding exon 10) of the IGSF3 gene. This alteration results from a G to T substitution at nucleotide position 3019, causing the alanine (A) at amino acid position 1007 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
