Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2024The c.481C>A (p.R161S) alteration is located in exon 1 (coding exon 1) of the KRTAP4-6 gene. This alteration results from a C to A substitution at nucleotide position 481, causing the arginine (R) at amino acid position 161 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
