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 Benign. Variant got -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.44).

BP6

Variant 17-31356467-G-A is Benign according to our data. Variant chr17-31356467-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 233929.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr17-31356467-G-A is described in Lovd as [Benign]. Variant chr17-31356467-G-A is described in Lovd as [Likely_benign].

BP7

Synonymous conserved (PhyloP=3.37 with no splicing effect.

BS2

High AC in GnomAdExome4 at 9 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
