Genes affected

CCDC65 (HGNC:29937): (coiled-coil domain containing 65) This gene encodes a sperm tail protein that is highly expressed in adult testis, spermatocytes and spermatids. The protein plays a critical role in the assembly of the nexin-dynein regulatory complex. Mutations in this gene result in primary ciliary dyskinesia. [provided by RefSeq, Nov 2013]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 474643). This variant has not been reported in the literature in individuals affected with CCDC65-related conditions. This variant is present in population databases (rs371110225, gnomAD 0.004%). This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 25 of the CCDC65 protein (p.Leu25Met). -
