Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.157T>C (p.Y53H) alteration is located in exon 1 (coding exon 1) of the KRTAP13-3 gene. This alteration results from a T to C substitution at nucleotide position 157, causing the tyrosine (Y) at amino acid position 53 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
