Genes affected

YME1L1 (HGNC:12843): (YME1 like 1 ATPase) The protein encoded by this gene is the human ortholog of yeast mitochondrial AAA metalloprotease, Yme1p. It is localized in the mitochondria and can functionally complement a yme1 disruptant yeast strain. It is proposed that this gene plays a role in mitochondrial protein metabolism and could be involved in mitochondrial pathologies. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), YME1L1. . Gene score misZ 2.5125 (greater than the threshold 3.09). Trascript score misZ 3.2015 (greater than threshold 3.09). GenCC has associacion of gene with autosomal recessive optic atrophy, optic atrophy 11.
• BP4: Computational evidence support a benign effect (MetaRNN=0.2019499).

This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 705 of the YME1L1 protein (p.Asp705Glu). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with YME1L1-related conditions. This variant is not present in population databases (gnomAD no frequency). -
