Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.493G>A (p.G165S) alteration is located in exon 3 (coding exon 3) of the TMEM86B gene. This alteration results from a G to A substitution at nucleotide position 493, causing the glycine (G) at amino acid position 165 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
