Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.16G>C (p.A6P) alteration is located in exon 1 (coding exon 1) of the SNED1 gene. This alteration results from a G to C substitution at nucleotide position 16, causing the alanine (A) at amino acid position 6 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
