Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.73A>G (p.I25V) alteration is located in exon 3 (coding exon 2) of the TMEM266 gene. This alteration results from a A to G substitution at nucleotide position 73, causing the isoleucine (I) at amino acid position 25 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
