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 Likely_benign. Variant got -5 ACMG points.

BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.00164 (119/72680) while in subpopulation SAS AF= 0.00577 (44/7632). AF 95% confidence interval is 0.00441. There are 0 homozygotes in gnomad4_exome. There are 80 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 119 AD gene.
