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]

Ambry Genetics

Oct 14, 2021

The c.377T>C (p.M126T) alteration is located in exon 6 (coding exon 6) of the SUN5 gene. This alteration results from a T to C substitution at nucleotide position 377, causing the methionine (M) at amino acid position 126 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
