Genes affected

CEND1 (HGNC:24153): (cell cycle exit and neuronal differentiation 1) The protein encoded by this gene is a neuron-specific protein. The similar protein in pig enhances neuroblastoma cell differentiation in vitro and may be involved in neuronal differentiation in vivo. Multiple pseudogenes have been reported for this gene.

The c.265G>A (p.D89N) alteration is located in exon 2 (coding exon 1) of the CEND1 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the aspartic acid (D) at amino acid position 89 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
