Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2022The c.298C>G (p.L100V) alteration is located in exon 4 (coding exon 3) of the TMEM266 gene. This alteration results from a C to G substitution at nucleotide position 298, causing the leucine (L) at amino acid position 100 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
