Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2024The c.319T>C (p.C107R) alteration is located in exon 6 (coding exon 4) of the TMEM63C gene. This alteration results from a T to C substitution at nucleotide position 319, causing the cysteine (C) at amino acid position 107 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
