Genes affected
FSIP2 (HGNC:21675): (fibrous sheath interacting protein 2) This gene encodes a protein associated with the sperm fibrous sheath. Genes encoding most of the fibrous-sheath associated proteins genes are transcribed only during the postmeiotic period of spermatogenesis. The protein encoded by this gene is specific to spermatogenic cells. Copy number variation in this gene may be associated with testicular germ cell tumors. Pseudogenes associated with this gene are reported on chromosomes 2 and X. [provided by RefSeq, Aug 2016]
FSIP2-AS1 (HGNC:40978): (FSIP2 antisense RNA 1)

The c.1417G>T (p.V473F) alteration is located in exon 10 (coding exon 10) of the FSIP2 gene. This alteration results from a G to T substitution at nucleotide position 1417, causing the valine (V) at amino acid position 473 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
