Genes affected
RAC2 (HGNC:9802): (Rac family small GTPase 2) This gene encodes a member of the Ras superfamily of small guanosine triphosphate (GTP)-metabolizing proteins. The encoded protein localizes to the plasma membrane, where it regulates diverse processes, such as secretion, phagocytosis, and cell polarization. Activity of this protein is also involved in the generation of reactive oxygen species. Mutations in this gene are associated with neutrophil immunodeficiency syndrome. There is a pseudogene for this gene on chromosome 6. [provided by RefSeq, Jul 2013]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.545C>T (p.T182M) alteration is located in exon 6 (coding exon 6) of the RAC2 gene. This alteration results from a C to T substitution at nucleotide position 545, causing the threonine (T) at amino acid position 182 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
