Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.575C>T (p.P192L) alteration is located in exon 4 (coding exon 3) of the CHMP7 gene. This alteration results from a C to T substitution at nucleotide position 575, causing the proline (P) at amino acid position 192 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
