Collection Method: clinical testing

The c.142C>T (p.H48Y) alteration is located in exon 3 (coding exon 3) of the RNF175 gene. This alteration results from a C to T substitution at nucleotide position 142, causing the histidine (H) at amino acid position 48 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
