Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.763A>G (p.M255V) alteration is located in exon 7 (coding exon 7) of the EXOSC7 gene. This alteration results from a A to G substitution at nucleotide position 763, causing the methionine (M) at amino acid position 255 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
