Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.73G>A (p.V25M) alteration is located in exon 3 (coding exon 1) of the TMEM169 gene. This alteration results from a G to A substitution at nucleotide position 73, causing the valine (V) at amino acid position 25 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
