Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The c.335A>G (p.N112S) alteration is located in exon 2 (coding exon 1) of the CHD9 gene. This alteration results from a A to G substitution at nucleotide position 335, causing the asparagine (N) at amino acid position 112 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
