Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.327T>G (p.I109M) alteration is located in exon 6 (coding exon 5) of the C2orf80 gene. This alteration results from a T to G substitution at nucleotide position 327, causing the isoleucine (I) at amino acid position 109 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
