Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2023The c.389T>C (p.L130P) alteration is located in exon 1 (coding exon 1) of the KRTAP13-3 gene. This alteration results from a T to C substitution at nucleotide position 389, causing the leucine (L) at amino acid position 130 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
