Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.1049G>A (p.S350N) alteration is located in exon 2 (coding exon 1) of the CHD9 gene. This alteration results from a G to A substitution at nucleotide position 1049, causing the serine (S) at amino acid position 350 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
