ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 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), EIF4A2. . Gene score misZ 3.895 (greater than the threshold 3.09). Trascript score misZ 5.45 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with hypotonia and speech delay, with or without seizures.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.767

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.464T>C (p.I155T) alteration is located in exon 5 (coding exon 5) of the EIF4A2 gene. This alteration results from a T to C substitution at nucleotide position 464, causing the isoleucine (I) at amino acid position 155 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
