Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.734A>T (p.Q245L) alteration is located in exon 3 (coding exon 3) of the USP43 gene. This alteration results from a A to T substitution at nucleotide position 734, causing the glutamine (Q) at amino acid position 245 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
