Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.127T>C (p.S43P) alteration is located in exon 1 (coding exon 1) of the KRTAP4-6 gene. This alteration results from a T to C substitution at nucleotide position 127, causing the serine (S) at amino acid position 43 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
