Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.436A>G (p.S146G) alteration is located in exon 2 (coding exon 2) of the CALHM3 gene. This alteration results from a A to G substitution at nucleotide position 436, causing the serine (S) at amino acid position 146 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
