Genes affected
NF1 (HGNC:7765): (neurofibromin 1) This gene product appears to function as a negative regulator of the ras signal transduction pathway. Mutations in this gene have been linked to neurofibromatosis type 1, juvenile myelomonocytic leukemia and Watson syndrome. The mRNA for this gene is subject to RNA editing (CGA>UGA->Arg1306Term) resulting in premature translation termination. Alternatively spliced transcript variants encoding different isoforms have also been described for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2
Missense variant in the NF1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 399 curated pathogenic missense variants (we use a threshold of 10). The gene has 143 curated benign missense variants. Gene score misZ: 6.5427 (above the threshold of 3.09). Trascript score misZ: 8.4054 (above the threshold of 3.09). GenCC associations: The gene is linked to neurofibromatosis, familial spinal, hereditary pheochromocytoma-paraganglioma, neurofibromatosis type 1, Watson syndrome, neurofibromatosis-Noonan syndrome, Moyamoya disease, familial ovarian cancer.
BP6
Variant 17-31350255-A-G is Benign according to our data. Variant chr17-31350255-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 41677.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Benign=1, Uncertain_significance=2}.
BS2
High AC in GnomAdExome4 at 34 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

​<span style="background-color:initial">Thep.D2465G<span style="background-color:initial"> variant (also known as c.7394A>G), located in coding exon 50 of theNF1<span style="background-color:initial"> gene, results from an A to G substitution at nucleotide position 7394. The aspartic acid at codon 2465 is replaced by glycine, an amino acid with similar properties. This alteration was previously reported and classified as a variant of uncertain significance in 1/572 individuals undergoing exome sequencing due to an atherosclerosis phenotype. This cohort was not selected based on a personal or family history of cancer (Johnston JJ, Am. J. Hum. Genet<span style="background-color:initial">. 2012 Jul; 91(1):97-108). This alteration is also known as c.7331A>G or p.D2444G in the literature due to differences in isoform. This variant was previously reported in the SNPDatabase as rs143474365. Based on data from the NHLBI Exome Sequencing Project (ESP), the G allele has an overall frequency of approximately 0.01% (1/13006) total alleles studied, having been detected in 0.01% (1/8600) European American alleles.<span style="background-color:initial">This variant was not reported in the 1000 Genomes Project population-based cohort.<span style="background-color:initial">To date, this alteration has been detected with an allele frequency of approximately 0.01% (greater than 55000 alleles tested) in our clinical cohort. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be benign and tolerated by PolyPhen and SIFTin silico<span style="background-color:initial"> analyses, respectively. Since supporting evidence is limited at this time, the clinical significance of p.D2465G remains unclear. -

Mar 02, 2018
Ambry Genetics
Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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. -
