Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_023013.4(PRAMEF1):​c.14C>G​(p.Ala5Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000275 in 1,455,488 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A5S) has been classified as Uncertain significance.

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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.074943155).
