Ambry Genetics

Feb 27, 2024

The c.82A>C (p.I28L) alteration is located in exon 1 (coding exon 1) of the TMEM44 gene. This alteration results from a A to C substitution at nucleotide position 82, causing the isoleucine (I) at amino acid position 28 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
