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

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.0019774735).
• BP6: Variant 1-12793956-A-G is Benign according to our data. Variant chr1-12793956-A-G is described in ClinVar as [Benign]. Clinvar id is 403339.Status of the report is criteria_provided_single_submitter, 1 stars.
