Genes affected

LY75 (HGNC:6729): (lymphocyte antigen 75) Predicted to enable signaling receptor activity. Predicted to be involved in immune response and inflammatory response. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

LY75 links:

LY75-CD302 (HGNC:38828): (LY75-CD302 readthrough) This locus represents naturally occurring read-through transcription between the neighboring lymphocyte antigen 75 (LY75) and CD302 molecule (CD302) genes. Alternative splicing results in multiple transcript variants encoding fusion products that share sequence identity with each individual gene product. [provided by RefSeq, Nov 2010]

Ambry Genetics

Aug 20, 2024

The c.5053G>A (p.G1685R) alteration is located in exon 35 (coding exon 35) of the LY75 gene. This alteration results from a G to A substitution at nucleotide position 5053, causing the glycine (G) at amino acid position 1685 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
