Genes affected

DNAH14 (HGNC:2945): (dynein axonemal heavy chain 14) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. Two major classes of dyneins, axonemal and cytoplasmic, have been identified. DNAH14 is an axonemal dynein heavy chain (DHC) (Vaughan et al., 1996 [PubMed 8812413]).[supplied by OMIM, Mar 2008]

Reported in an individual who harbored a second DNAH14 variant in trans; however they also harbored a de novo variant in AHDC1 which may explain their phenotype (Khayat et al., 2021); Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene or region of a gene for which loss of function is not a well-established mechanism of disease; This variant is associated with the following publications: (PMID: 34950897) -
