Genes affected
LTN1 (HGNC:13082): (listerin E3 ubiquitin protein ligase 1) Like most RING finger proteins, LTN1 functions as an E3 ubiquitin ligase (Chu et al., 2009 [PubMed 19196968]).[supplied by OMIM, Nov 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.4468A>G (p.I1490V) alteration is located in exon 25 (coding exon 25) of the LTN1 gene. This alteration results from a A to G substitution at nucleotide position 4468, causing the isoleucine (I) at amino acid position 1490 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
