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-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]

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.22).
• BP7: Synonymous conserved (PhyloP=0.006 with no splicing effect.
