Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.146C>T (p.P49L) alteration is located in exon 3 (coding exon 1) of the TMEM106B gene. This alteration results from a C to T substitution at nucleotide position 146, causing the proline (P) at amino acid position 49 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
