Test ID DWPAN Comprehensive Distal Weakness Gene Panel, Varies


Ordering Guidance


Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. See FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.

 

Customization of this panel and single gene analysis for any gene present on this panel are available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.



Shipping Instructions

Useful For

Establishing a molecular diagnosis for patients with distal weakness

 

Identifying variants within genes known to be associated with distal weakness, allowing for predictive testing of at-risk family members

Genetics Test Information

This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 212 genes associated with distal weakness: AAAS, AARS1, ABCA1, ABCD1, ACTA1, AIFM1, ALDH18A1, AMACR, ANO5, AP5Z1, APOA1, APTX, ARSA, ATL1, ATL3, ATM, ATP1A1, ATP7A, B4GALNT1, BAG3, BICD2, BIN1, BSCL2, C12orf65 (MTRFR), C1orf194, CAV3, CHCHD10, CLCF1, CLTCL1, CNTNAP1, COQ4, COQ7, COX10, COX20, COX6A1, CPOX, CRLF1, CRYAB, CTDP1, CYP27A1, CYP2U1, CYP7B1, DCTN1, DDHD1, DES, DGAT2, DHH, DNAJB2, DNAJB6, DNM2, DNMT1, DST, DYNC1H1, DYSF, EGR2, ELP1, ERCC8, FA2H, FAM126A, FBLN5, FBXO38, FDX2, FGD4, FGF14, FHL1, FIG4, FLNC, FLVCR1, FMR1, FXN, GALC, GAN, GARS1, GBA2, GBE1, GBF1, GDAP1, GJB1, GLA, GM2A, GNB4, GNE, GSN, HADHA, HADHB, HARS1, HEXA, HEXB, HINT1, HK1, HMBS, HNRNPA1, HNRNPA2B1, HSPB1, HSPB8, HSPD1, IARS2, IBA57, IGHMBP2, INF2, KARS1, KIF1A, KIF5A, LAMA2, LDB3, LITAF, LMNA, LRSAM1, MARS1, MATR3, MCM3AP, MFN2, MME, MORC2, MPC1, MPV17, MPZ, MTMR2, MTTP, MYH14, MYH2, MYH7, MYOT, NAGLU, NDRG1, NEB, NEFH, NEFL, NF2, NGF, NIPA1, NTRK1, OPA1, PDK3, PDYN, PEX7, PHYH, PLA2G6, PLEKHG5, PLP1, PMP2, PMP22, PNKP, PNPLA6, POLG, PPOX, PRDM12, PRKCG, PRNP, PRPS1, PRX, PTRH2, RAB7A, REEP1, RETREG1, RNASEH1, RRM2B, RTN2, SACS, SBF1, SBF2, SCN10A, SCN11A, SCN9A, SCO2, SELENON, SEPTIN9, SETX, SH3TC2, SIGMAR1, SLC12A6, SLC25A19, SLC25A46, SLC52A2, SLC52A3, SLC5A7, SNAP29, SOD1, SORD, SOX10, SPAST, SPG11, SPG21, SPG7, SPTAN1, SPTLC1, SPTLC2, SQSTM1, SUCLA2, SURF1, TDP1, TFG, TIA1, TRIM2, TRPV4, TSFM, TTN, TTPA, TTR, TUBB3, TWNK, TYMP, UBA1, VCP, VPS13D, VRK1, VWA1, WARS1, WASHC5, WNK1, YARS1, ZFYVE26. SMN1 exon 7 and SMN2 exon 7 copy number are determined by droplet digital polymerase chain reaction. See Targeted Genes and Methodology Details for Comprehensive Distal Weakness Gene Panel and Method Description for additional details.

 

Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, recurrence risk assessment, familial screening, and genetic counseling for distal weakness.
