Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.202G>A (p.G68R) alteration is located in exon 1 (coding exon 1) of the KRTAP5-8 gene. This alteration results from a G to A substitution at nucleotide position 202, causing the glycine (G) at amino acid position 68 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
