Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2022The c.194G>C (p.G65A) alteration is located in exon 3 (coding exon 3) of the HN1L gene. This alteration results from a G to C substitution at nucleotide position 194, causing the glycine (G) at amino acid position 65 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
