Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP6BS2_Supporting

The NM_001042492.3(NF1):​c.7742C>G​(p.Thr2581Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000235 in 1,613,738 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). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T2581A) 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 -2 ACMG points.

BP6
Variant 17-31356963-C-G is Benign according to our data. Variant chr17-31356963-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 186257.
BS2
High AC in GnomAdExome4 at 37 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
