Genes affected

BTN3A2 (HGNC:1139): (butyrophilin subfamily 3 member A2) This gene encodes a member of the immunoglobulin superfamily, which resides in the juxta-telomeric region of the major histocompatability class 1 locus and is clustered with the other family members on chromosome 6. The encoded protein may be involved in the adaptive immune response. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The c.350C>T (p.T117I) alteration is located in exon 4 (coding exon 2) of the BTN3A2 gene. This alteration results from a C to T substitution at nucleotide position 350, causing the threonine (T) at amino acid position 117 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
