Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.37C>A (p.P13T) alteration is located in exon 3 (coding exon 1) of the CTXN3 gene. This alteration results from a C to A substitution at nucleotide position 37, causing the proline (P) at amino acid position 13 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
