Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.1099A>G (p.S367G) alteration is located in exon 8 (coding exon 8) of the CHPT1 gene. This alteration results from a A to G substitution at nucleotide position 1099, causing the serine (S) at amino acid position 367 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
