Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2024The c.392C>T (p.T131M) alteration is located in exon 2 (coding exon 2) of the SNED1 gene. This alteration results from a C to T substitution at nucleotide position 392, causing the threonine (T) at amino acid position 131 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
