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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2024The c.562G>T (p.A188S) 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 562, causing the alanine (A) at amino acid position 188 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
