Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 25, 2022The c.337C>G (p.P113A) alteration is located in exon 2 (coding exon 2) of the KRTAP2-2 gene. This alteration results from a C to G substitution at nucleotide position 337, causing the proline (P) at amino acid position 113 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
