Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.203A>G (p.N68S) alteration is located in exon 1 (coding exon 1) of the HCAR2 gene. This alteration results from a A to G substitution at nucleotide position 203, causing the asparagine (N) at amino acid position 68 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
