Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.22T>A (p.S8T) alteration is located in exon 1 (coding exon 1) of the SLC44A1 gene. This alteration results from a T to A substitution at nucleotide position 22, causing the serine (S) at amino acid position 8 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
