Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.511G>C (p.D171H) alteration is located in exon 1 (coding exon 1) of the CHSY3 gene. This alteration results from a G to C substitution at nucleotide position 511, causing the aspartic acid (D) at amino acid position 171 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
