Collection Method: clinical testing

The c.10312C>A (p.Q3438K) alteration is located in exon 80 (coding exon 80) of the USP34 gene. This alteration results from a C to A substitution at nucleotide position 10312, causing the glutamine (Q) at amino acid position 3438 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
