Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.415G>T (p.V139L) alteration is located in exon 3 (coding exon 3) of the SLC35F3 gene. This alteration results from a G to T substitution at nucleotide position 415, causing the valine (V) at amino acid position 139 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
