Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The NM_001366028.2(DNAH12):c.9639G>A(p.Leu3213=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. L3213L) has been classified as Benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: DNAH12 NM_001366028.2 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.183

Genes affected

DNAH12 (HGNC:2943): (dynein axonemal heavy chain 12) Predicted to enable several functions, including ATP binding activity; dynein intermediate chain binding activity; and dynein light intermediate chain binding activity. Predicted to be involved in microtubule-based movement. Predicted to be located in cilium; cytoplasm; and microtubule. Predicted to be part of dynein complex.

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.29).
• BP7: Synonymous conserved (PhyloP=-0.183 with no splicing effect.
