Genes affected

CIAPIN1 (HGNC:28050): (cytokine induced apoptosis inhibitor 1) CIAPIN1 is a cytokine-induced inhibitor of apoptosis with no relation to apoptosis regulatory molecules of the BCL2 (MIM 151430) or CASP (see MIM 147678) families. Expression of CIAPIN1 is dependent on growth factor stimulation (Shibayama et al., 2004 [PubMed 14970183]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.350C>T (p.S117L) alteration is located in exon 4 (coding exon 3) of the CIAPIN1 gene. This alteration results from a C to T substitution at nucleotide position 350, causing the serine (S) at amino acid position 117 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
