Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.818T>A (p.V273D) alteration is located in exon 3 (coding exon 3) of the C6orf118 gene. This alteration results from a T to A substitution at nucleotide position 818, causing the valine (V) at amino acid position 273 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
