Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2021The c.315G>T (p.Q105H) alteration is located in exon 1 (coding exon 1) of the KRTAP2-3 gene. This alteration results from a G to T substitution at nucleotide position 315, causing the glutamine (Q) at amino acid position 105 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
