Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.641T>C (p.I214T) alteration is located in exon 2 (coding exon 2) of the CHPF2 gene. This alteration results from a T to C substitution at nucleotide position 641, causing the isoleucine (I) at amino acid position 214 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
