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]
SUN5 Gene-Disease associations (from GenCC):
  • spermatogenic failure 16

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 15 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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.958
PP5
Variant 20-32983868-G-A is Pathogenic according to our data. Variant chr20-32983868-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 268048.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
