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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.3360G>C (p.E1120D) alteration is located in exon 11 (coding exon 10) of the IGSF3 gene. This alteration results from a G to C substitution at nucleotide position 3360, causing the glutamic acid (E) at amino acid position 1120 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
