Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 3P and 6B. PM2PP2BP4_StrongBP6_Moderate

The NM_001007237.3(IGSF3):c.3320G>A(p.Arg1107His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000483 in 1,572,408 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1107C) has been classified as Uncertain significance.

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]

Ambry Genetics

Sep 20, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
