The c.668C>T (p.P223L) alteration is located in exon 8 (coding exon 6) of the TMEM150B gene. This alteration results from a C to T substitution at nucleotide position 668, causing the proline (P) at amino acid position 223 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
