Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.380G>C (p.S127T) alteration is located in exon 4 (coding exon 4) of the CHURC1 gene. This alteration results from a G to C substitution at nucleotide position 380, causing the serine (S) at amino acid position 127 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
