Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.625C>G (p.L209V) alteration is located in exon 6 (coding exon 4) of the MTCL1 gene. This alteration results from a C to G substitution at nucleotide position 625, causing the leucine (L) at amino acid position 209 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
