Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.56T>C (p.L19P) alteration is located in exon 1 (coding exon 1) of the TRAK1 gene. This alteration results from a T to C substitution at nucleotide position 56, causing the leucine (L) at amino acid position 19 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
