Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2023The c.1581C>A (p.D527E) alteration is located in exon 16 (coding exon 13) of the TMCO4 gene. This alteration results from a C to A substitution at nucleotide position 1581, causing the aspartic acid (D) at amino acid position 527 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
