Genes affected

ELAVL4 (HGNC:3315): (ELAV like RNA binding protein 4) Enables mRNA 3'-UTR AU-rich region binding activity; poly(A) binding activity; and pre-mRNA intronic pyrimidine-rich binding activity. Involved in 3'-UTR-mediated mRNA stabilization; RNA processing; and positive regulation of 3'-UTR-mediated mRNA stabilization. Predicted to be located in axon; cytoplasm; and dendrite. Predicted to be part of polysomal ribosome. Predicted to be active in glutamatergic synapse. [provided by Alliance of Genome Resources, Apr 2022]

The c.308G>A (p.S103N) alteration is located in exon 3 (coding exon 3) of the ELAVL4 gene. This alteration results from a G to A substitution at nucleotide position 308, causing the serine (S) at amino acid position 103 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
