Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2021The c.145A>G (p.I49V) alteration is located in exon 3 (coding exon 3) of the TMEM190 gene. This alteration results from a A to G substitution at nucleotide position 145, causing the isoleucine (I) at amino acid position 49 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
