Genes affected

PRAMEF1 (HGNC:28840): (PRAME family member 1) This gene is a member of the PRAME (preferentially expressed antigen of melanoma) gene family which is expressed in many cancers but may function in reproductive tissues during development. Alternative promoter usage generates two transcript variants, which encode different isoforms. [provided by RefSeq, Jun 2014]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
