Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.227A>G (p.Q76R) alteration is located in exon 2 (coding exon 2) of the EVA1C gene. This alteration results from a A to G substitution at nucleotide position 227, causing the glutamine (Q) at amino acid position 76 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
