Genes affected
DNAL1 (HGNC:23247): (dynein axonemal light chain 1) This gene encodes an axonemal dynein light chain which functions as a component of the outer dynein arms complex. This complex acts as the molecular motor that provides the force to move cilia in an ATP-dependent manner. The encoded protein is expressed in tissues with motile cilia or flagella and may be involved in the movement of sperm flagella. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jan 2011]

The DNAL1 c.415C>G; p.Leu139Val variant (rs141873943; ClinVar Variation ID: 178765) has been observed in a cohort of patients referred for Bronchiectasis, but no additional evidence of causality was provided (Olm 2019). This variant is found in the Latino population with an allele frequency of 0.34% (88/25652 alleles) in the Genome Aggregation Database. The leucine at codon 139 is highly conserved, but computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.241). Due to limited information, the clinical significance of the p.Leu139Val variant is uncertain at this time. References: Olm MAK et al. Severe pulmonary disease in an adult primary ciliary dyskinesia population in Brazil. Sci Rep. 2019 Jun 18;9(1):8693. PMID: 31213628 -
