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: Pathogenic. The variant received 22 ACMG points.

PVS1
Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
PS3
PS3 evidence extracted from ClinVar submissions: SCV007097379: Classified as Pathogenic per ACMG/AMP criteria (PVS1, PM2, PS3_supporting).
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 17-31338733-CACTT-C is Pathogenic according to our data. Variant chr17-31338733-CACTT-C is described in ClinVar as Pathogenic. ClinVar VariationId is 216866.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
