Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.25C>G (p.L9V) alteration is located in exon 1 (coding exon 1) of the C12orf10 gene. This alteration results from a C to G substitution at nucleotide position 25, causing the leucine (L) at amino acid position 9 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
