Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.414A>C (p.E138D) alteration is located in exon 6 (coding exon 6) of the THOC7 gene. This alteration results from a A to C substitution at nucleotide position 414, causing the glutamic acid (E) at amino acid position 138 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
