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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2024The c.1384G>A (p.V462M) alteration is located in exon 1 (coding exon 1) of the RTL1 gene. This alteration results from a G to A substitution at nucleotide position 1384, causing the valine (V) at amino acid position 462 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
