Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 3P and 7B. PM1PP2BP4_ModerateBP6BS2
The NM_001042492.3(NF1):c.6442G>A(p.Val2148Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000155 in 1,613,828 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. V2148V) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome;CN230736:Cardiovascular phenotype Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 12, 2021 | This alteration is classified as likely benign based on a combination of the following: 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. - |
