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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.205A>C (p.N69H) alteration is located in exon 1 (coding exon 1) of the FSIP2 gene. This alteration results from a A to C substitution at nucleotide position 205, causing the asparagine (N) at amino acid position 69 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
