Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.409G>A (p.A137T) 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 409, causing the alanine (A) at amino acid position 137 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
