Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2022The c.667G>A (p.A223T) alteration is located in exon 2 (coding exon 2) of the SLC35E4 gene. This alteration results from a G to A substitution at nucleotide position 667, causing the alanine (A) at amino acid position 223 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
