The c.1316A>G (p.Q439R) alteration is located in exon 14 (coding exon 11) of the USP37 gene. This alteration results from a A to G substitution at nucleotide position 1316, causing the glutamine (Q) at amino acid position 439 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
