NCIt definition : A genetic finding indicating that a subject expresses the HA-1(H) genotype and has
a homozygous or heterozygous nucleotide substitution at position 416 of the ARHGAP45
gene where the guanine has been mutated to adenine, which encodes a variant of Rho
GTPase-activating protein 45 where the arginine at position 139 has been replaced
by histidine. The HA-1(H) form of ARHGAP45 protein can be processed into a nonapeptide
that can be presented by HLA-A*0201 and other HLA-A isoforms, while the peptide produced
by processing the protein resulting from transcription of the ARHGAP45 gene with guanine
at position 416, which will have arginine at amino acid residue 139 (HA-1(R)) cannot
bind HLA-A.;
