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]

The c.1519C>T (p.R507C) alteration is located in exon 1 (coding exon 1) of the RTL1 gene. This alteration results from a C to T substitution at nucleotide position 1519, causing the arginine (R) at amino acid position 507 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
