Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.450C>G (p.I150M) alteration is located in exon 1 (coding exon 1) of the KRTAP13-3 gene. This alteration results from a C to G substitution at nucleotide position 450, causing the isoleucine (I) at amino acid position 150 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
