Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.401C>G (p.P134R) alteration is located in exon 1 (coding exon 1) of the KRTAP13-4 gene. This alteration results from a C to G substitution at nucleotide position 401, causing the proline (P) at amino acid position 134 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
