Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.1231G>T (p.V411L) alteration is located in exon 10 (coding exon 9) of the CHMP7 gene. This alteration results from a G to T substitution at nucleotide position 1231, causing the valine (V) at amino acid position 411 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
