Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2021The c.3160G>A (p.G1054R) alteration is located in exon 12 (coding exon 12) of the REXO1 gene. This alteration results from a G to A substitution at nucleotide position 3160, causing the glycine (G) at amino acid position 1054 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
