Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2021The c.2528T>C (p.L843P) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a T to C substitution at nucleotide position 2528, causing the leucine (L) at amino acid position 843 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
