Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2022The c.1630C>T (p.R544C) alteration is located in exon 16 (coding exon 13) of the TMCO4 gene. This alteration results from a C to T substitution at nucleotide position 1630, causing the arginine (R) at amino acid position 544 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
