Genes affected
DRC4 (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]
URAHP (HGNC:43695): (urate (hydroxyiso-) hydrolase, pseudogene) Predicted to enable hydroxyisourate hydrolase activity. Predicted to be involved in allantoin metabolic process; purine-containing compound catabolic process; and urate catabolic process. Predicted to be active in peroxisome.

This sequence change replaces aspartic acid with asparagine at codon 433 of the GAS8 protein (p.Asp433Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs150016330, ExAC 0.02%). This variant has not been reported in the literature in individuals affected with GAS8-related conditions. 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 C0"). 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. -

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

The c.1297G>A (p.D433N) alteration is located in exon 11 (coding exon 11) of the GAS8 gene. This alteration results from a G to A substitution at nucleotide position 1297, causing the aspartic acid (D) at amino acid position 433 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
