Genes affected
DNAH2 (HGNC:2948): (dynein axonemal heavy chain 2) 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. DNAH2 is an axonemal inner arm dynein heavy chain (Chapelin et al., 1997 [PubMed 9256245]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.601C>A (p.L201M) alteration is located in exon 4 (coding exon 4) of the DNAH2 gene. This alteration results from a C to A substitution at nucleotide position 601, causing the leucine (L) at amino acid position 201 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
