Genes affected

CELF4 (HGNC:14015): (CUGBP Elav-like family member 4) 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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.5).
• BP6: Variant 18-37273035-T-C is Benign according to our data. Variant chr18-37273035-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 3038143.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP7: Synonymous conserved (PhyloP=-0.268 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 9 AD gene.
