not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.683G>A (p.R228H) alteration is located in exon 5 (coding exon 4) of the TXLNA gene. This alteration results from a G to A substitution at nucleotide position 683, causing the arginine (R) at amino acid position 228 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
