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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.628G>T (p.D210Y) alteration is located in exon 5 (coding exon 5) of the ROPN1L gene. This alteration results from a G to T substitution at nucleotide position 628, causing the aspartic acid (D) at amino acid position 210 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
