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.

Collection Method: clinical testing

The c.302C>G (p.A101G) alteration is located in exon 2 (coding exon 1) of the CEND1 gene. This alteration results from a C to G substitution at nucleotide position 302, causing the alanine (A) at amino acid position 101 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
