Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.61A>G (p.M21V) alteration is located in exon 7 (coding exon 1) of the SGMS1 gene. This alteration results from a A to G substitution at nucleotide position 61, causing the methionine (M) at amino acid position 21 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
