not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.889C>T (p.H297Y) alteration is located in exon 9 (coding exon 9) of the RTFDC1 gene. This alteration results from a C to T substitution at nucleotide position 889, causing the histidine (H) at amino acid position 297 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
