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: Benign. The variant received -20 ACMG points.

BP4
This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 2 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.76).
BP6
Variant 17-31352228-G-A is Benign according to our data. Variant chr17-31352228-G-A is described in ClinVar as [Benign]. Clinvar id is 257303.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr17-31352228-G-A is described in Lovd as [Benign].
BA1
GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.615 is higher than 0.05.
