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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PM1

In a topological_domain Perinuclear space (size 256) in uniprot entity SUN5_HUMAN there are 4 pathogenic changes around while only 1 benign (80%) in NM_080675.4

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 4 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.68847 (below the threshold of 3.09). Trascript score misZ: 0.63256 (below the threshold of 3.09). GenCC associations: The gene is linked to spermatogenic failure 16.

BP4

Computational evidence support a benign effect (MetaRNN=0.05767122).

The c.1018G>C (p.V340L) 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 1018, causing the valine (V) at amino acid position 340 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
