Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2022The c.91A>C (p.M31L) alteration is located in exon 2 (coding exon 1) of the CHMP7 gene. This alteration results from a A to C substitution at nucleotide position 91, causing the methionine (M) at amino acid position 31 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
