Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2022The c.436C>T (p.L146F) alteration is located in exon 4 (coding exon 4) of the TEX26 gene. This alteration results from a C to T substitution at nucleotide position 436, causing the leucine (L) at amino acid position 146 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
