Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.1426A>C (p.I476L) alteration is located in exon 17 (coding exon 17) of the SDAD1 gene. This alteration results from a A to C substitution at nucleotide position 1426, causing the isoleucine (I) at amino acid position 476 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
