Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2021The c.383C>G (p.A128G) alteration is located in exon 2 (coding exon 1) of the SMCO3 gene. This alteration results from a C to G substitution at nucleotide position 383, causing the alanine (A) at amino acid position 128 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
