The c.427C>T (p.H143Y) alteration is located in exon 2 (coding exon 1) of the TMEM239 gene. This alteration results from a C to T substitution at nucleotide position 427, causing the histidine (H) at amino acid position 143 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
