Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 2P and 6B. PM1BP4_StrongBP6BS2_Supporting

The NM_001042492.3(NF1):c.7213A>G(p.Ile2405Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000118 in 1,605,186 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I2405S) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PM1

In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 30 uncertain in NM_001042492.3

BP4

Computational evidence support a benign effect (MetaRNN=0.051487297).

BP6

Variant 17-31349143-A-G is Benign according to our data. Variant chr17-31349143-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 186162.

BS2

High AC in GnomAdExome4 at 17 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
