Genes affected

EFL1 (HGNC:25789): (elongation factor like GTPase 1) Enables GTPase activity and ribosome binding activity. Involved in GTP metabolic process and mature ribosome assembly. Predicted to be part of ribonucleoprotein complex. Implicated in Shwachman-Diamond syndrome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.847

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 disruptive. This variant has not been reported in the literature in individuals affected with EFL1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1068 of the EFL1 protein (p.Pro1068Leu). -
