Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_001326339.2(CELF2):​c.-51A>G variant causes a 5 prime UTR premature start codon gain change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

CELF2 (HGNC:2550): (CUGBP Elav-like family member 2) Members of the CELF/BRUNOL protein family contain two N-terminal RNA recognition motif (RRM) domains, one C-terminal RRM domain, and a divergent segment of 160-230 aa between the second and third RRM domains. Members of this protein family regulate pre-mRNA alternative splicing and may also be involved in mRNA editing, and translation. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.797

The heterozygous p.Tyr74Cys variant in CELF2 was identified by our study in 1 individual with a neurodevelopmental disorder. While this gene is still lacking sufficient evidence to establish a gene-disease relationship, we believe this is a possible novel gene candidate for neurodevelopmental disorders. Given the limited information about this gene-disease relationship, the significance of the p.Tyr74Cys variant is uncertain. If you have any additional information about functional evidence or other individuals with this phenotype that also have variants in CELF2 we encourage you to reach out to us. -
