Genes affected

TDRD7 (HGNC:30831): (tudor domain containing 7) The protein encoded by this gene belongs to the Tudor family of proteins. This protein contains conserved Tudor domains and LOTUS domains. It is a component of RNA granules, which function in RNA processing. Mutations in this gene have been associated with cataract formation in mouse and human. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

The c.293G>A (p.G98E) alteration is located in exon 3 (coding exon 2) of the TDRD7 gene. This alteration results from a G to A substitution at nucleotide position 293, causing the glycine (G) at amino acid position 98 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
