Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.518C>T (p.S173F) 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 518, causing the serine (S) at amino acid position 173 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
