The c.181C>T (p.H61Y) alteration is located in exon 2 (coding exon 2) of the TMEM260 gene. This alteration results from a C to T substitution at nucleotide position 181, causing the histidine (H) at amino acid position 61 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
