The c.2003T>G (p.I668S) alteration is located in exon 12 (coding exon 12) of the TMEM8A gene. This alteration results from a T to G substitution at nucleotide position 2003, causing the isoleucine (I) at amino acid position 668 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
