Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2022The c.305C>A (p.P102H) alteration is located in exon 3 (coding exon 2) of the KATNAL1 gene. This alteration results from a C to A substitution at nucleotide position 305, causing the proline (P) at amino acid position 102 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
