Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.433T>C (p.C145R) alteration is located in exon 6 (coding exon 6) of the MTG1 gene. This alteration results from a T to C substitution at nucleotide position 433, causing the cysteine (C) at amino acid position 145 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
