Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.415G>A (p.V139M) alteration is located in exon 7 (coding exon 5) of the TMEM98 gene. This alteration results from a G to A substitution at nucleotide position 415, causing the valine (V) at amino acid position 139 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
