Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2024The c.1033C>A (p.P345T) alteration is located in exon 2 (coding exon 1) of the CHD9 gene. This alteration results from a C to A substitution at nucleotide position 1033, causing the proline (P) at amino acid position 345 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
