Genes affected
FSIP2-AS2 (HGNC:54061): (FSIP2 antisense RNA 2)
FSIP2-AS1 (HGNC:40978): (FSIP2 antisense RNA 1)
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.149G>A (p.G50D) alteration is located in exon 1 (coding exon 1) of the FSIP2 gene. This alteration results from a G to A substitution at nucleotide position 149, causing the glycine (G) at amino acid position 50 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
