The c.88C>T (p.H30Y) alteration is located in exon 1 (coding exon 1) of the TMEM178B gene. This alteration results from a C to T substitution at nucleotide position 88, causing the histidine (H) at amino acid position 30 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
