Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2023The c.544G>A (p.G182S) alteration is located in exon 7 (coding exon 7) of the TMEM255B gene. This alteration results from a G to A substitution at nucleotide position 544, causing the glycine (G) at amino acid position 182 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
