The variant allele was found at a frequency of 0.313 in 152,084 control chromosomes in the GnomAD database, including 7,702 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.31 (7702 hom., cov: 32)
• Consequence: LTN1 NM_015565.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -3.07

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.339 is higher than 0.05.
