The c.1949T>A (p.L650H) alteration is located in exon 14 (coding exon 13) of the TMEM232 gene. This alteration results from a T to A substitution at nucleotide position 1949, causing the leucine (L) at amino acid position 650 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
