Genes affected

GPATCH8 (HGNC:29066): (G-patch domain containing 8) The protein encoded by this gene contains an RNA-processing domain, a zinc finger domain, a lysine-rich region and a serine-rich region. A mutation in the serine-rich region of the protein is thought to be associated with hyperuricemia (PMID: 21594610). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2015]

The c.3510A>T (p.E1170D) alteration is located in exon 8 (coding exon 8) of the GPATCH8 gene. This alteration results from a A to T substitution at nucleotide position 3510, causing the glutamic acid (E) at amino acid position 1170 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
