not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.303G>T (p.M101I) alteration is located in exon 4 (coding exon 4) of the HN1 gene. This alteration results from a G to T substitution at nucleotide position 303, causing the methionine (M) at amino acid position 101 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
