Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.424A>T (p.M142L) alteration is located in exon 2 (coding exon 2) of the SLAIN2 gene. This alteration results from a A to T substitution at nucleotide position 424, causing the methionine (M) at amino acid position 142 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
