Genes affected

RTL1 (HGNC:14665): (retrotransposon Gag like 1) This gene is a retrotransposon-derived, paternally expressed imprinted gene that is highly expressed at the late fetal stage in both the fetus and placenta. It has an overlapping maternally expressed antisense transcript, which contains several microRNAs targeting the transcripts of this gene through an RNA interference (RNAi) mechanism. This gene is essential for maintenance of the fetal capillaries. [provided by RefSeq, Jul 2009]

MEG8 (HGNC:14574): (maternally expressed 8, small nucleolar RNA host gene) This gene is located in a cluster of imprinted genes on chromosome 14q32.3. It encodes a a non-protein coding transcript that is preferentially expressed from the maternal allele in skeletal muscle, and appears to be coordinately regulated with other imprinted genes in this region. [provided by RefSeq, Oct 2010]

MIR493HG (HGNC:55978): (MIR493 cluster host gene)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.044713974).
