Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2022The c.412C>T (p.R138C) alteration is located in exon 3 (coding exon 3) of the EVA1C gene. This alteration results from a C to T substitution at nucleotide position 412, causing the arginine (R) at amino acid position 138 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
