The c.1910G>A (p.R637H) alteration is located in exon 7 (coding exon 7) of the TTLL11 gene. This alteration results from a G to A substitution at nucleotide position 1910, causing the arginine (R) at amino acid position 637 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
