Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.295A>G (p.S99G) alteration is located in exon 4 (coding exon 2) of the TMEM169 gene. This alteration results from a A to G substitution at nucleotide position 295, causing the serine (S) at amino acid position 99 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
