Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.212C>T (p.T71M) alteration is located in exon 3 (coding exon 2) of the HMP19 gene. This alteration results from a C to T substitution at nucleotide position 212, causing the threonine (T) at amino acid position 71 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
