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.

Ambry Genetics

Nov 19, 2022

The c.760T>C (p.F254L) alteration is located in exon 2 (coding exon 1) of the ZCCHC5 gene. This alteration results from a T to C substitution at nucleotide position 760, causing the phenylalanine (F) at amino acid position 254 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
