Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.1316C>T (p.A439V) alteration is located in exon 13 (coding exon 11) of the GTF2H1 gene. This alteration results from a C to T substitution at nucleotide position 1316, causing the alanine (A) at amino acid position 439 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
