Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2PP2PP3PP5
The ENST00000633077.2(CELF2):c.1558C>T(p.Pro520Ser) variant causes a missense 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. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P520L) has been classified as Uncertain significance.
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]
Verdict is Uncertain_significance. Variant got 5 ACMG points.
PM2
