Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.456T>G (p.I152M) alteration is located in exon 6 (coding exon 6) of the THOC7 gene. This alteration results from a T to G substitution at nucleotide position 456, causing the isoleucine (I) at amino acid position 152 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
