Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.947G>A (p.R316H) alteration is located in exon 7 (coding exon 7) of the KCMF1 gene. This alteration results from a G to A substitution at nucleotide position 947, causing the arginine (R) at amino acid position 316 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
