Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2024The c.200T>C (p.L67P) alteration is located in exon 4 (coding exon 3) of the TMEM71 gene. This alteration results from a T to C substitution at nucleotide position 200, causing the leucine (L) at amino acid position 67 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
