Genes affected

EVI2A (HGNC:3499): (ecotropic viral integration site 2A) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

EVI2A links:

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]

Ambry Genetics

Apr 12, 2022

The c.518C>A (p.T173N) alteration is located in exon 3 (coding exon 2) of the EVI2A gene. This alteration results from a C to A substitution at nucleotide position 518, causing the threonine (T) at amino acid position 173 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
