Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2023The c.1411C>T (p.R471C) alteration is located in exon 15 (coding exon 12) of the TMCO4 gene. This alteration results from a C to T substitution at nucleotide position 1411, causing the arginine (R) at amino acid position 471 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
