Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.737C>T (p.P246L) alteration is located in exon 2 (coding exon 2) of the SLC35E4 gene. This alteration results from a C to T substitution at nucleotide position 737, causing the proline (P) at amino acid position 246 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
