Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 11, 2023The c.868C>T (p.L290F) 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 868, causing the leucine (L) at amino acid position 290 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
