Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.431G>C (p.C144S) alteration is located in exon 1 (coding exon 1) of the KRTAP4-8 gene. This alteration results from a G to C substitution at nucleotide position 431, causing the cysteine (C) at amino acid position 144 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
