Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.364A>C (p.S122R) alteration is located in exon 2 (coding exon 1) of the CHD9 gene. This alteration results from a A to C substitution at nucleotide position 364, causing the serine (S) at amino acid position 122 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
