Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 06, 2024 | The c.383C>G (p.A128G) alteration is located in exon 4 (coding exon 3) of the ARMC4 gene. This alteration results from a C to G substitution at nucleotide position 383, causing the alanine (A) at amino acid position 128 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
Primary ciliary dyskinesia 23 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 31, 2021 | This sequence change replaces alanine with glycine at codon 128 of the ARMC4 protein (p.Ala128Gly). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with ARMC4-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. - |
