Genes affected

EVI2B (HGNC:3500): (ecotropic viral integration site 2B) Involved in positive regulation of granulocyte differentiation. Predicted to be integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

EVI2B 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

Jul 05, 2024

The c.708A>T (p.Q236H) alteration is located in exon 2 (coding exon 1) of the EVI2B gene. This alteration results from a A to T substitution at nucleotide position 708, causing the glutamine (Q) at amino acid position 236 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
