Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2021The c.1562G>A (p.R521H) alteration is located in exon 16 (coding exon 13) of the TMCO4 gene. This alteration results from a G to A substitution at nucleotide position 1562, causing the arginine (R) at amino acid position 521 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
