Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 05, 2022The c.326G>T (p.R109L) alteration is located in exon 1 (coding exon 1) of the SLC35E4 gene. This alteration results from a G to T substitution at nucleotide position 326, causing the arginine (R) at amino acid position 109 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
