Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2022The c.573C>G (p.C191W) alteration is located in exon 4 (coding exon 3) of the CHMP7 gene. This alteration results from a C to G substitution at nucleotide position 573, causing the cysteine (C) at amino acid position 191 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
