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]

The c.3379C>T (p.R1127C) alteration is located in exon 11 (coding exon 10) of the IGSF3 gene. This alteration results from a C to T substitution at nucleotide position 3379, causing the arginine (R) at amino acid position 1127 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
