Genes affected

DNAH10 (HGNC:2941): (dynein axonemal heavy chain 10) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. The axonemal dyneins, found in cilia and flagella, are components of the outer and inner dynein arms attached to the peripheral microtubule doublets. DNAH10 is an inner arm dynein heavy chain (Maiti et al., 2000 [PubMed 11175280]).[supplied by OMIM, Mar 2008]

LOC105370044 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.17174882).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.260G>C (p.C87S) alteration is located in exon 4 (coding exon 4) of the DNAH10 gene. This alteration results from a G to C substitution at nucleotide position 260, causing the cysteine (C) at amino acid position 87 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
