Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2021The c.103C>T (p.P35S) alteration is located in exon 2 (coding exon 1) of the CMTR1 gene. This alteration results from a C to T substitution at nucleotide position 103, causing the proline (P) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
