Genes affected

CCIN (HGNC:1568): (calicin) The protein encoded by this gene is a basic protein of the sperm head cytoskeleton. This protein contains kelch repeats and a BTB/POZ domain and is necessary for normal morphology during sperm differentiation. This gene is intronless. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.341C>G (p.P114R) alteration is located in exon 1 (coding exon 1) of the CCIN gene. This alteration results from a C to G substitution at nucleotide position 341, causing the proline (P) at amino acid position 114 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
