Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.709A>G (p.I237V) alteration is located in exon 9 (coding exon 6) of the TMCO4 gene. This alteration results from a A to G substitution at nucleotide position 709, causing the isoleucine (I) at amino acid position 237 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
