Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 13, 2023The c.197T>C (p.I66T) alteration is located in exon 4 (coding exon 4) of the MTA3 gene. This alteration results from a T to C substitution at nucleotide position 197, causing the isoleucine (I) at amino acid position 66 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
