Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2022The c.409C>A (p.L137I) alteration is located in exon 3 (coding exon 3) of the TMEM42 gene. This alteration results from a C to A substitution at nucleotide position 409, causing the leucine (L) at amino acid position 137 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
