Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.176A>G (p.N59S) alteration is located in exon 6 (coding exon 3) of the FOCAD gene. This alteration results from a A to G substitution at nucleotide position 176, causing the asparagine (N) at amino acid position 59 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 59 of the FOCAD protein (p.Asn59Ser). This variant is present in population databases (rs764916026, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with FOCAD-related conditions. ClinVar contains an entry for this variant (Variation ID: 2485399). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Not Available"; Align-GVGD: "Not Available". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
