Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2023The c.829G>A (p.V277M) alteration is located in exon 10 (coding exon 9) of the CHID1 gene. This alteration results from a G to A substitution at nucleotide position 829, causing the valine (V) at amino acid position 277 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
