Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.784G>A (p.G262S) alteration is located in exon 3 (coding exon 3) of the CALHM3 gene. This alteration results from a G to A substitution at nucleotide position 784, causing the glycine (G) at amino acid position 262 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
