Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 24, 2024The c.817T>C (p.S273P) alteration is located in exon 7 (coding exon 6) of the KATNAL1 gene. This alteration results from a T to C substitution at nucleotide position 817, causing the serine (S) at amino acid position 273 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
