Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2022The c.499G>A (p.A167T) alteration is located in exon 6 (coding exon 6) of the CHCHD6 gene. This alteration results from a G to A substitution at nucleotide position 499, causing the alanine (A) at amino acid position 167 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
