Genes affected
GAS8 (HGNC:4166): (growth arrest specific 8) This gene includes 11 exons spanning 25 kb and maps to a region of chromosome 16 that is sometimes deleted in breast and prostrate cancer. The second intron contains an apparently intronless gene, C16orf3, that is transcribed in the opposite orientation. This gene is a putative tumor suppressor gene. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2013]

Primary ciliary dyskinesia 33 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 25, 2022This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 29 of the GAS8 protein (p.Glu29Lys). This variant is present in population databases (rs560531650, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with GAS8-related conditions. ClinVar contains an entry for this variant (Variation ID: 572231). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). 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. -
