Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.838G>A (p.G280S) alteration is located in exon 9 (coding exon 7) of the GTF2H1 gene. This alteration results from a G to A substitution at nucleotide position 838, causing the glycine (G) at amino acid position 280 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
