Genes affected

ACIN1 (HGNC:17066): (apoptotic chromatin condensation inducer 1) Apoptosis is defined by several morphologic nuclear changes, including chromatin condensation and nuclear fragmentation. This gene encodes a nuclear protein that induces apoptotic chromatin condensation after activation by caspase-3, without inducing DNA fragmentation. This protein has also been shown to be a component of a splicing-dependent multiprotein exon junction complex (EJC) that is deposited at splice junctions on mRNAs, as a consequence of pre-mRNA splicing. It may thus be involved in mRNA metabolism associated with splicing. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

The c.3530G>A (p.R1177Q) alteration is located in exon 17 (coding exon 17) of the ACIN1 gene. This alteration results from a G to A substitution at nucleotide position 3530, causing the arginine (R) at amino acid position 1177 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
