Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.1166G>C (p.C389S) alteration is located in exon 10 (coding exon 7) of the GTDC1 gene. This alteration results from a G to C substitution at nucleotide position 1166, causing the cysteine (C) at amino acid position 389 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
