Genes affected

RTL3 (HGNC:22997): (retrotransposon Gag like 3) This gene is a member of a family of gag-related retrotransposon genes. These genes appear to have lost the ability to retrotranspose; however, their open reading frames have remained intact, which may indicate that these genes have acquired new functions in the cell.

Jul 11, 2023

The c.1262C>T (p.P421L) alteration is located in exon 2 (coding exon 1) of the ZCCHC5 gene. This alteration results from a C to T substitution at nucleotide position 1262, causing the proline (P) at amino acid position 421 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
