Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.317G>A (p.R106H) alteration is located in exon 5 (coding exon 5) of the TMEM190 gene. This alteration results from a G to A substitution at nucleotide position 317, causing the arginine (R) at amino acid position 106 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
