Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.500C>T (p.P167L) alteration is located in exon 2 (coding exon 2) of the SEZ6L gene. This alteration results from a C to T substitution at nucleotide position 500, causing the proline (P) at amino acid position 167 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
