Ambry Genetics

Nov 18, 2022

The c.2285C>T (p.S762L) alteration is located in exon 24 (coding exon 22) of the TMEM63A gene. This alteration results from a C to T substitution at nucleotide position 2285, causing the serine (S) at amino acid position 762 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
