Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2022The c.67G>A (p.G23S) alteration is located in exon 1 (coding exon 1) of the KRTAP5-5 gene. This alteration results from a G to A substitution at nucleotide position 67, causing the glycine (G) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
