Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.433T>C (p.Y145H) alteration is located in exon 2 (coding exon 2) of the C3orf70 gene. This alteration results from a T to C substitution at nucleotide position 433, causing the tyrosine (Y) at amino acid position 145 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
