Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.38G>C (p.R13P) alteration is located in exon 1 (coding exon 1) of the PTCD3 gene. This alteration results from a G to C substitution at nucleotide position 38, causing the arginine (R) at amino acid position 13 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
