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.

Ambry Genetics

Aug 15, 2023

The c.293C>T (p.S98L) 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 293, causing the serine (S) at amino acid position 98 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
