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]

Submissions by phenotype

Primary ciliary dyskinesia 33 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 04, 2023This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 22 of the GAS8 protein (p.Ala22Thr). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GAS8 protein function. ClinVar contains an entry for this variant (Variation ID: 542262). This variant has not been reported in the literature in individuals affected with GAS8-related conditions. This variant is present in population databases (rs762664716, gnomAD 0.002%). -
