Genes affected
SUN5 (HGNC:16252): (Sad1 and UNC84 domain containing 5) The protein encoded by this gene appears to play a role in the meiotic stage of spermatogenesis. The encoded protein localizes to the junction between the sperm head and body and may be involved in nuclear envelope reconstitution and nuclear migration. Mutations in this gene have been implicated in acephalic spermatozoa syndrome. [provided by RefSeq, May 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.1075G>C (p.V359L) alteration is located in exon 13 (coding exon 13) of the SUN5 gene. This alteration results from a G to C substitution at nucleotide position 1075, causing the valine (V) at amino acid position 359 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
