Genes affected

EML1 (HGNC:3330): (EMAP like 1) Human echinoderm microtubule-associated protein-like is a strong candidate for the Usher syndrome type 1A gene. Usher syndromes (USHs) are a group of genetic disorders consisting of congenital deafness, retinitis pigmentosa, and vestibular dysfunction of variable onset and severity depending on the genetic type. The disease process in USHs involves the entire brain and is not limited to the posterior fossa or auditory and visual systems. The USHs are catagorized as type I (USH1A, USH1B, USH1C, USH1D, USH1E and USH1F), type II (USH2A and USH2B) and type III (USH3). The type I is the most severe form. Gene loci responsible for these three types are all mapped. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 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), EML1. . Gene score misZ 2.4519 (greater than the threshold 3.09). Trascript score misZ 3.3424 (greater than threshold 3.09). GenCC has associacion of gene with band heterotopia of brain, subcortical band heterotopia.

BP4

Computational evidence support a benign effect (MetaRNN=0.10608408).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000889 (13/1461884) while in subpopulation EAS AF= 0.000252 (10/39700). AF 95% confidence interval is 0.000136. There are 0 homozygotes in gnomad4_exome. There are 7 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Ambry Genetics

Dec 05, 2022

The c.293A>G (p.N98S) alteration is located in exon 3 (coding exon 3) of the EML1 gene. This alteration results from a A to G substitution at nucleotide position 293, causing the asparagine (N) at amino acid position 98 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
