Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2022The c.451C>T (p.R151C) alteration is located in exon 5 (coding exon 5) of the CHCHD6 gene. This alteration results from a C to T substitution at nucleotide position 451, causing the arginine (R) at amino acid position 151 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
