Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 24, 2023 | The c.349C>A (p.P117T) alteration is located in exon 1 (coding exon 1) of the PROX2 gene. This alteration results from a C to A substitution at nucleotide position 349, causing the proline (P) at amino acid position 117 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
