Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.130C>G (p.P44A) alteration is located in exon 1 (coding exon 1) of the TRNP1 gene. This alteration results from a C to G substitution at nucleotide position 130, causing the proline (P) at amino acid position 44 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
