Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.766G>A (p.V256M) alteration is located in exon 5 (coding exon 5) of the C16orf78 gene. This alteration results from a G to A substitution at nucleotide position 766, causing the valine (V) at amino acid position 256 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
