Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 15, 2023 | The c.1106G>C (p.R369P) alteration is located in exon 10 (coding exon 9) of the TCHP gene. This alteration results from a G to C substitution at nucleotide position 1106, causing the arginine (R) at amino acid position 369 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
