Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2022The c.836C>T (p.T279I) 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 836, causing the threonine (T) at amino acid position 279 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
