Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.311C>T (p.A104V) alteration is located in exon 3 (coding exon 3) of the EXOSC5 gene. This alteration results from a C to T substitution at nucleotide position 311, causing the alanine (A) at amino acid position 104 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
