Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2024The c.317C>T (p.T106I) alteration is located in exon 3 (coding exon 3) of the TMEM86B gene. This alteration results from a C to T substitution at nucleotide position 317, causing the threonine (T) at amino acid position 106 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
