Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2024The c.1906C>G (p.P636A) alteration is located in exon 21 (coding exon 21) of the SDAD1 gene. This alteration results from a C to G substitution at nucleotide position 1906, causing the proline (P) at amino acid position 636 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
