Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.319G>A (p.G107S) alteration is located in exon 4 (coding exon 4) of the TMEM255B gene. This alteration results from a G to A substitution at nucleotide position 319, causing the glycine (G) at amino acid position 107 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
