Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.1442G>A (p.G481D) alteration is located in exon 15 (coding exon 12) of the TMCO4 gene. This alteration results from a G to A substitution at nucleotide position 1442, causing the glycine (G) at amino acid position 481 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
