Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.3863A>G (p.K1288R) alteration is located in exon 27 (coding exon 27) of the SNED1 gene. This alteration results from a A to G substitution at nucleotide position 3863, causing the lysine (K) at amino acid position 1288 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
