Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2022The c.45G>C (p.M15I) alteration is located in exon 2 (coding exon 2) of the SAMD13 gene. This alteration results from a G to C substitution at nucleotide position 45, causing the methionine (M) at amino acid position 15 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
