Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2021The c.435A>G (p.I145M) alteration is located in exon 6 (coding exon 6) of the C12orf40 gene. This alteration results from a A to G substitution at nucleotide position 435, causing the isoleucine (I) at amino acid position 145 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
