May 06, 2024

The c.292T>C (p.F98L) alteration is located in exon 4 (coding exon 1) of the TMEM100 gene. This alteration results from a T to C substitution at nucleotide position 292, causing the phenylalanine (F) at amino acid position 98 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
