Variant summary
Our verdict is Benign. Variant got -14 ACMG points: 2P and 16B. PM5BP4_StrongBP6_Very_StrongBS2
The NM_176787.5(PIGN):āc.2238A>Gā(p.Ile746Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0012 in 1,611,218 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I746R) has been classified as Likely pathogenic.

Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 27, 2018 | 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. - |
