Genes affected

LONRF3 (HGNC:21152): (LON peptidase N-terminal domain and ring finger 3) The protein encoded by this gene contains a RING finger domain, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions. Multiple alternatively spliced transcript variants have been suggested, but their full length natures are not clear. [provided by RefSeq, Jul 2008]

Ambry Genetics

Nov 27, 2023

The c.463G>T (p.G155C) alteration is located in exon 1 (coding exon 1) of the LONRF3 gene. This alteration results from a G to T substitution at nucleotide position 463, causing the glycine (G) at amino acid position 155 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
