Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.521G>A (p.R174H) alteration is located in exon 2 (coding exon 2) of the CALHM3 gene. This alteration results from a G to A substitution at nucleotide position 521, causing the arginine (R) at amino acid position 174 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
