Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.25G>A (p.G9R) alteration is located in exon 2 (coding exon 1) of the TMEM104 gene. This alteration results from a G to A substitution at nucleotide position 25, causing the glycine (G) at amino acid position 9 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
