Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.56A>C (p.E19A) alteration is located in exon 3 (coding exon 1) of the SMIM8 gene. This alteration results from a A to C substitution at nucleotide position 56, causing the glutamic acid (E) at amino acid position 19 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
