Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4BP7BS1

This summary comes from the ClinGen Evidence Repository: The NM_002524.5:c.112-8A>G variant is an intronic variant that is not predicted by SpliceAI to impact splicing. In addition, it occurs at a nucleotide that is not conserved as shown by UCSC Genome Browser (BP4, BP7). The filtering allele frequency (the lower threshold of the 95% CI of 62/127294) of the c.112-8A>G variant in NRAS is 0.0003711 for European (non-Finnish) chromosomes by gnomAD v2.1.1, which is higher than the ClinGen RASopathy VCEP threshold (≥0.00025) for BS1, and therefore meets this criterion (BS1). In summary, this variant meets the criteria to be classified as likely benign for autosomal dominant RASopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen RASopathy VCEP: BS1, BP4, BP7.

Genes affected
NRAS (HGNC:7989): (NRAS proto-oncogene, GTPase) This is an N-ras oncogene encoding a membrane protein that shuttles between the Golgi apparatus and the plasma membrane. This shuttling is regulated through palmitoylation and depalmitoylation by the ZDHHC9-GOLGA7 complex. The encoded protein, which has intrinsic GTPase activity, is activated by a guanine nucleotide-exchange factor and inactivated by a GTPase activating protein. Mutations in this gene have been associated with somatic rectal cancer, follicular thyroid cancer, autoimmune lymphoproliferative syndrome, Noonan syndrome, and juvenile myelomonocytic leukemia.
