Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 20, 2024The c.137C>A (p.A46D) alteration is located in exon 3 (coding exon 1) of the SLC14A1 gene. This alteration results from a C to A substitution at nucleotide position 137, causing the alanine (A) at amino acid position 46 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
