Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.219C>A (p.D73E) alteration is located in exon 4 (coding exon 2) of the GTF2H1 gene. This alteration results from a C to A substitution at nucleotide position 219, causing the aspartic acid (D) at amino acid position 73 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
