About DNAH11

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.

In silico prediction tools support a deleterious effect: REVEL score is 0.887, which exceeds the 0.75 threshold for damaging prediction. BayesDel score is 0.43 (intermediate). SpliceAI predicts no splicing impact (max delta = 0.00). The REVEL score provides supporting computational evidence of pathogenicity.

Benign criteria applied · 0

No benign criterion marked as applied in the recorded assessment.

Recorded classification: Uncertain significance

gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM2 supporting, PP3 supporting; combination = 2 supporting, which maps to VUS.

NM_001277115.2:c.4879C>T (p.Arg1627Cys) is a missense variant in DNAH11, a gene associated with autosomal recessive primary ciliary dyskinesia (PCD) and heterotaxy syndromes.

This variant is extremely rare in population databases: gnomAD v2.1 AF = 0.00107% (3/280,426 alleles), gnomAD v4.1 AF = 0.00155% (25/1,613,592 alleles), and it is absent from gnomAD-Canada, with no homozygotes observed in any population database (PM2_supporting).

In silico prediction tools support a deleterious effect, with a REVEL score of 0.887 exceeding the damaging threshold (PP3_supporting).

SpliceAI predicts no splicing impact (max delta score = 0.00), and the variant does not lie in a statistically significant mutational hotspot.

This variant has been reported in ClinVar with conflicting classifications: four clinical laboratories classify it as Uncertain Significance, one as Pathogenic, and one as Likely Pathogenic. No expert panel review has been performed (ClinVar Variation ID: 163104).

The variant has been observed somatically in COSMIC (COSV60977423, n = 2).

No variant-specific functional data, case-control studies, segregation data, or de novo reports were identified in the reviewed literature. The five publications cited by ClinVar submitters are either methodology/guideline papers (PMID:24033266, PMID:25741868, PMID:28492532), a general GeneReviews overview (PMID:20301301), or a PCD cohort study that does not specifically mention c.4879C>T (PMID:31772028).
