Genes affected

ROPN1L (HGNC:24060): (rhophilin associated tail protein 1 like) This gene encodes a member of the ropporin family. The encoded protein is present in sperm and interacts with A-kinase anchoring protein, AKAP3, through the amphipathic helix region of AKAP3. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2014]

Collection Method: clinical testing

The c.431C>T (p.A144V) alteration is located in exon 4 (coding exon 4) of the ROPN1L gene. This alteration results from a C to T substitution at nucleotide position 431, causing the alanine (A) at amino acid position 144 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
