Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.496G>A (p.V166M) alteration is located in exon 4 (coding exon 4) of the EXOSC5 gene. This alteration results from a G to A substitution at nucleotide position 496, causing the valine (V) at amino acid position 166 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
