Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.352G>A (p.V118M) alteration is located in exon 2 (coding exon 2) of the CHPF2 gene. This alteration results from a G to A substitution at nucleotide position 352, causing the valine (V) at amino acid position 118 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
