Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.233A>T (p.Q78L) alteration is located in exon 2 (coding exon 1) of the CHMP7 gene. This alteration results from a A to T substitution at nucleotide position 233, causing the glutamine (Q) at amino acid position 78 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
